Cs-Cart Affiliate Catalog Mod

In Cs-cart I need a modification that will display a Buy Now button next to the product details. The buy now button needs to redirect via javascript to the affiliate product (mask the link in javascript). I use cs-cart in catalog mode as I want to use it for affiliate products which are uploaded by csv to the store. But there is no affiliate function in cscart to add affiliate products via a datafeed. Ability to upload the product details with the new field so I can just import from a datafeed from an affiliate network. The buy now button needs to be placed where I specify next to the product image/code number. Please answer this simple maths question 3 + 4 = Please post answer in your reply! Or I will consider your offer. Will need database mod with additional field. I am open to a better method but I am essentially after the ability easily upload affiliate products from affiliate netword datafeeds in csv format. A masked external link to the affiliate product and a buy now button placed next to product where I specify with the clickable being the masked affiliate link as metioned previously. All mods need to be easily rolled out by myself to many other cscart installs I have and future installs. So detailed instructionsn will be required so I suggest keeping mods as simple as possible. Skills Required: php, JavaScript, mysql
