Add Feature to ASP Affiliate Software

Hi, I have acquired a shopping cart/affiliate software that works very well, except that I want to pay affiliates via PayPal and it does not have that feature. The task is to add the paypal feature and I want to be able to do the affiliate commission payments via the admin section. This project should be very easy for someone who is very familiar with ASP and Windows Servers. I can provide more information via PMB.
