im having some trouble creating some npcs for my game any ideas how would be appreciated

What kind of npcs do you want?

Someone posted a bit ago some tables to help roll quick NPC's.

Use the npc's in the books, FFG covers a broad range of types. These can also be modified for better customization and personalization.

+1 to this.

You can use the stats from another NPC but change the description and flavor text.

Who's to know that the construction dude zombie is really using the stats from the dog zombie in another scenario?

And as the players get more savvy and better equipped, don't be afraid to adjust some stats on the fly to make it a bit more challenging.
