44403 Versign Payment PHP

Here's the project, purchased a copy of E-commerce software named IMSCART, come to find that it is a resale of a hacked version of PHPShop, I need to complete the ecommerce application, which include, adding a Versign Payflow Pro Credit Card Processsing to the cart, and fix the UPS live quote system that is installed. Everything else in the Application seems to be working good. Unfounatey I need to get this done with the next couple of days. So it is a very tight deadline job. I am looking for someone to fix and make the modules necessary to get this site working with a very quick turnaround. It is very important that the person doing the work has experience with ecommerce and PHP to get this done. --------------------------------------------------------------------------------
