Custom Affiliate Store Script

I need a custom affiliate store script with similar features like [login to view URL] or [login to view URL] Those websites work with amazon and eBay, however i want my script to work with [login to view URL] I want the script allows me to select any category i want from [login to view URL] by keywords. The script also must has 'affiliate program tracking cookie' feature where even if my website visitor leaves my website and buys nothing, I still get paid when they return to [login to view URL] later to buy ANY item. The script must 'match' with my website design and my programmer can install it. I will give the URL of my website to successful bidder. My budget is $30. Higher bid will be ignored (this is a simple script, I know how much it cost). Payment via GAF escrow and will be released upon project completion. No advance.
