Custom Poker Chip Website or add to a website

I need a add on to our current wesbite or a seperate site. This would be for a custom poker chips. The customer would come to the site pick the color of poker chip, color of text and font and would also be able to add a graphic. basically they design there own poker chip right on the website. This is similar to what some custom t-shirt and other products sites are doing. Please have experience in making this type of site and send examples in your pm with your bid.
