PAYPAL IPN module for shopping cart

Development of a PHP module to use PAYPAL IPN. I have the shopping cart already and all that I need is a module that get the checkout and use the IPN. I know it's easy and there is a lot of FREE modules out there, but I don't have the time to modify and test it. YOU DO THIS FOR ME. My shopping cart is for multiple items and the checkout have the option payment to be processed locally (money order/checks) or sent to Paypal once. Once means, all data will be sent in multiple items one time, not sending updates to Paypal cart. Just one final communication with Paypal with all items in the cart. Module MUST come with all instructions on how to be agregated to my cart. Any question? * Please don't bid if you had no previous experience with IPN ## Deliverables 1) Complete and fully-functional working script(s) as complete and VERY WELL commented source code of all work done. 2) Deliverables must be in ready-to-run condition with all information on how to be called from the shopping cart's checkout and interpreted response from PAYPAL. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
