AlertPay API/IPN: Integration with s2member.

Needing a Simple Alertpay Integration to s2Member. Customer pays a One-Time-Fee using the Alertpay Button, after Successful Payment, the customer will have access to the Members only area. The Members area is already setup as well as the "Member Options" page (where the AlertPay Payment Buttons will be located at), so we ONLY need the Integration done. Very Simple and Straight forward: The Coder needs to setup only one Alertpay Button on the "Member Options" page, and make sure that the customer has access to the Membership level they paid for after payment has been processed. Coder also needs to show me how and where to change the variables in the code in case we need to change the FEE in the near future. We need an "EXPERIENCED" coder to do this project quickly and efficiently. If we like your work, we will re-hire you for future projects!
