Repair Simple Shopping Script & Build Clones

I have a shopping script which is simply 1 page with options which allow customers to pay with paypal or 2co. The orders are logged in a control panel but for some reason the 2co function is not working correctly. I need this fixed and also require a simple affiliate program added (i will provide simple script) This is an hours work maximum for a experienced programmer. I will have future work over the next few weeks for the same programmer as we are looking to clone the site over and over MAXIMUM BIDS OF $30 AS YOUR ONLY FIXING NOT BUILDING!
