paypal pro integration and paypal express ipn debug

I wish to fix paypal checkout relay back (ipn) and also since I have merchant account with paypal, either fix or redo checkout with paypal pro without customer leaving the site. You can do it in Coldfusion or php. I will help, since I can code in CF. The database is simple, will explain what fields need updating from relay back on payment confirmation response. It all used to work before I switched to other payment gateway and after switching back to paypal, relay back stopped working. Server runs both paypal and cold fusion. You can check checkout on semiprecious.com. Just need cartid to relay back with paid status in cart table. Must be done by time you state you will do it. I will work with you to make it faster. Any improvements can be done is additional projects, I will also need this in [login to view URL] which only has stripe and no paypal...that will be a separate project.
