so it looks like people are interested in playing at my shop and have steady base of about 6 players with more coming. my friend is interested in having sealed and draft tournaments but its been forever since i've been in one so where can i find official rules on how to run it and how much to charge?

Go to the rules forum to download the universial rules faq. It has all your draft/sealed rules in there. How much to charge is up to your store.
