Build your own product feature

We need someone to help us create a "design your own product" feature for the website. It should be done using Javascript (not flash) and will eventually be integrated into magento product page. Just to give you an idea, the feature should look similar to the "customize your shoe" feature on the [login to view URL] site. Our product is more like an office chair than a shoe and I will provide all the necessary graphics. There will be about 9 color combinations and 4 texture combinations. So the user should be able to click on the texture + color and see a preview of the chair on the page. A completed work should just be an html file along with image and javascript files. I will integrate it into magento platform myself. If you know how to work with php to allow users select the colors to be added to magento cart that would also be helpful. If not, then we will exclude that functionality. *We are looking for a response right away
