Login & Registration System w/paypal integration

Looking to get some bids on a full login, registration & payment system for my site. All in HTML & PHP Basically looking for the following: 1.) Login form that will authenticate against a mysql database. 2.) Registration for for new users 2.5) mysql database driven 3.) ability to pick account level upon registration, with paypal payment (2 levels, 1 free and 1 paid) 4.) forgot password/username script 5.) OpenID integration 6.) account expiration upon registration date expiring 7.) session control for all member pages that would be accessed (a session statement should suffice) 8) css to support simple styling of forms 9) basic security with hashing of passwords etc ... Basically, looking for a full login/registration system. Does not have to be overly complex, but functional. If you have code you built before, we can probably leverage reusing it and implement on my site. We can discuss in more detail.
