Zen Cart small upgrade

I have zen cart Eshop. Everything is ready and set up.? I have 5 unique products there and each of them consist of html table with colors. When you click on color big thumbnail show the color sample. I need you to add PHP code and create variable for colors. Means if I add this product to the basket the color must get there as well.? Color variable must show everywhere (basket, checkout, invoice) If the customer wants to order different colors in the same time he will has to go back and make another order for the same product but different price. Thats all I need. I need this work ASAP. For successful coder I will have work on regular basis /zen cart but also another projects/ YOU MUST: - be able to start asap - have good knowledge and experience with Zen Cart, PHP, MySQL Place your bid with comments and I will send you the link to see the shop with products. Many Thanks
