536446 WePay Payment Gateway Wordpress Plugin

I need to get a basic WePay payment gateway integrated with the supporter plugin. The link to the WePay website is: [login to view URL] Basically, the user has to be able to: 1. Click on a "pay now" type button and go to WePay to make a payment. 2. Process the WePay Instant Payment Notification (IPN) and credit the user as Paid. 3. Return to the original website and continue. The Admin must be able to set basic features like: 1. wepay payment status: Live, Test, Off 2. enter API Key 3. Account name and email 4. Set payment types to 1-time or subscription 5. Create and enter as many "Pay Now" buttons are required. 6. Full class integration with the WePay API's using curl 7. other settings as necessary. 8. Reporting - view payments The User view: 1. view and sort user's payments 2. Make additional purchases The program that handles the IPN (Instant Payment Notification) from wepay. 1. Authenticate the post is truly from Wepay. 2. Call a function hook to credit the payer. (I will write the function that hooks in) Please contact me if you have prior experience with coding payment gateways and are interested and available to do this work.
