Well really what they're paying for is a Warp Route, and a sensor sweep that they could easily do themselves. The going rate for Warp Routes is 1 Profit Factor so... maybe with continuous and reliable information they could turn that into negotiating for 2 Profit Factor, but nothing really above that.

I can't imagine someone like Winterscale or Chorda ever making "friends", especially since their business relationship is entirely that of someone who goes to find places that are vaguely interesting but then leave all the work to them. Since they hate each other, if your players group with one the other will probably hate them just out of contrariness. At which point they will start actively working to sabotage the Dynasty and their relationship.

Basically, I am at a loss. I have no idea how they are suppose to make money this way, I mean, without a doubt we could do adventures like this until they all die horribly because I could keep coming up with something for them to fight and explore. So, any ideas on how I can make this work because I don't think the Endeavor system totally works for this kind of play, where they are basically scouts.

I am very much considering changing the game to DH or something like that if they really want to play the game this way, but that is just my thoughts.

Don't give up hope yet. There are a several routes that I can think of which could assist you with this.

1) The routes, planets, minerals, anomalies etc. the PC's discover are so unique and profitable, that other RT's now bid to get the information, with the highest bidder obtaining it. Obviously this won't happen initially, but maybe after awhile of them discovered such profitable places, other RT's starting bidding on it. For example: After their 7th trip into the Expanse, the PC's return to Footfall with a new route. Prior to docking, a buyer reaches out and contacts the PC's to purchase the information for a decent price. The PC's agree. Shortly after agreeing, the PC's receive another message asking to purchase their information. The PC's say "Sorry, already sold it." This buyer then says "I will pay double." And hence starts the bidding.

2) A buyer (or several) after purchasing a route, requests the PC's to conduct a specific endeavor as they do not have resources. The price they offer is substantial to make it interesting. These requests can be as simple as delivering supplies to a newly created colony, showing a VIP the asteroid they are planning to mine, to capturing a dangerous beast or wiping out a pirate hideout.

3) While investigating the ruins, a planet, an asteroid, etc, the PC’s discover something that is life changing. They could of accidently released a daemon, woke up a Yu’vath construct, disturbed some old bones and contracted a deadly disease that only affects humans with blue eyes and blonde hair, found a SM frozen in stasis, etc etc. Simply selling the route will not make this go away. Having this happen every single time the PC’s discover a new world would be less rewarding, so maybe after the 50 ^th one of so this could happen.

With all this said, it’s you and the players game though. If you feel they would like to play DH instead of RT, and everyone would get more enjoyment out of that (including you), then go with DH.

Rogue Trader does allow you to come up with sweeping, Expanse-wide plots of intrigue and espionage for your players to partake in, but as Nameless pointed out, there are still complications and challenges you can throw at your crew without your players expecting them, and maybe they just want to get them out of their system. I kind of like the idea of a Rogue Trader crew that wants a quiet, boring, steady way to make Profit Factor and connections but keeps running into political metaplots they wish they could ignore. Here's a few more!

4) One of the planets that they sold was an Eldar Maiden World, and they find themselves being relentlessly pursued by the forces of Craftworld Kaelor. They discover that the Stryxis might have a map of the systems with active Webway gates and would be pleased at the thought of screwing over the Eldar, but will have to track down the enigmatic creatures and then satisfy their bizarre whims before they can plan a counter-attack.

5) The planet is full of an apparently lost civilization of colonists of the Imperium of Mankind, whose technology didn't survive the colonisation but never the less they are eager to return and serve the Imperium once more. Either your players or whomever they sell this planet to can easily use them to replenish ship losses as humans are just another valuable resource in the Expanse. They're even not tainted with Chaos if a curious or genre-savvy Astropath starts scanning them for corruption. Too bad that's because they're tainted with Tyranid.

6) The planet has already been "sold" by another Rogue Trader doing the same thing, and a war between the two buyers plays out over the skies of the world, ruining its resources when a plasma drive erupts in near-orbit and causing an ecological catastrophe. Now both parties have put aside their differences to come asking for a refund. With guns. Lots of guns.

7) Necrons.

First Advrnture in RT? There you go:

Another option, along similar lines to those above, is to use a different, non-Rogue Trader party as the Colony Creators (based on the idea Chora and Winterscale wouldn't be interested). What if, for example, in your game-universe Damaris succeeded in becoming a recognized Imperial World. Then, say, the Administorum is now interested in establishing official outlying colonies around their new Koronus sub-sector capital. Or, in the case of your peculiar situation, perhaps the Administorum has claimed the RT's former colonies as well.

They might be willing to pay a Rogue Trader to find colonization sites (not just system scans, but actual "land colony here beacons") and resource surveys in the Damaris Region. There are several adventures you could have searching out planets or other items of interest and cataloguing them for the Administorum (or raiding them prior to handing them over).

As long as your players are enjoying the game, don't worry if they're not making truckloads of PF. In the fluff there are plenty of Rogue Trader generations that are perfectly happy if they can manage to end their life with the PF they started it with. Given that Rogue Traders can (with enough rolling) get some pretty good gear and keep themselves afloat without ever reducing their PF, it never really has to change.

I'd argue that scouting can be profitable, but with little-to-none for locations of systems unless they have blatantly obvious things like dyson spheres. Planetary scans and ground samples worth a hell of a lot more - proof!

Things like the locations of dead xenos hives and ships are worth thrones. Some great suggestions above for how that could go badly wrong.

So in short, what the players are doing can make them a living if not the fastest track to riches. But who knows what treasure they might stumble across!

I think it's worth adding in that an implicit understanding with this arrangement is that your PCs wouldn't be taking things from the planet they've discovered. Scouting out locations and valuable resources is somewhat viable, but the knowledge that you're selling the leftovers would probably rub a lot of Rogue Traders the wrong way.

They likely couldn't tell if you take gear for your PCs, but loading up your cargo hold with goods would probably be noticeable.
