Membership Login system with Facebook integration

Task (which should take no more than 2 hours for anyone who knows what he's doing): Create an asp.net Login Membership system that accepts Facebook user as the membership unique id (if a facebook user--if not, use email address), and uses mysql as the member database. There are two types of login memberships: Free and Paid. Free by default. Once a member, the user can choose to buy a paid membership through paypal. I already have 2 different projects--one that creates membership and accepts login; the other, that accepts paid memberships through paypal purchase--that you can use to modify and bring into one project towards development and completion of this small job.
