Help creating simple payment system.

[fearfx]

Ok, I am new to vbulletin. So my ? is:

I want a Registerd User to be able to purchase a TEAM PASS through paypal, using vbulletin. After that TEAM PASS is purchased, I would like the USER redirected to a page ONLY accessiable to REGISTERED USERS who have PURCHASED the TEAM PASS. Once they get to that page, I need them to put in some information: Like : Team name: Teams Rosters: 4 input fields. (for a team of 4 members). and maybe some contact info. Lastley, I would also like a new NAV link only to show for the people who have PAID for the team pass. So they can access there ROSTER page, and change team info if neccesary.

Any Ideas on how I should go about this?

Sorry but my spelling sucks.
