229974 Member site script

I need a simple script for lead generation. Here's how it should work: It will have 3 user group: 1) Admin, 2) Buyer, and 3) Seller. Admin will control everything, Buyers will have access to submit a request form and all Sellers will receive that request form with all information on it. Admin should be able to view all of the request, edit them if need be, delete them, approve or deny them. Buyers registers for free and Sellers will pay a fee via paypal to join. Admin must approve all registrations. For both users I need the following information: First Name, Last Name, Business Name, Service Provided, Address, City, State, Zip, Tel#, Fax#, Email Address, Website Address, Username, Password. I need "Forgort Password" option, "Remember me" and IP Location logging. Any questions, please feel free to ask.
