Multiple Paypal IPN Site

I was going to start coding myself but unfortunately don't have the time.. Please read carefully before reading. Don't bid unless you can meet all the requirements. (I've had bad experiences with coders who start a project and later stop and ask for more money..) I need a multiple IPN service site which is basically a site that will allow users who have multiple sites to use this service to bypass the current restiction that paypal has by allowing only a single IPN sscript. Basically It needs all the functionality that is offered at this site Please review carefully the following site, it options, how it works etc: [login to view URL] I NEED only the functionality. No design required, infact it can all be text. What's Required for this project - PHP with Mod_Rewritte - MySQL - Knowledge of how the paypal IPN works Once again is not difficult project. You will only take care on the functional, coding of the site, No web or graphic design.. Looking to start ASAP Thanks
