Custom Shirt E-commerce

Hello everyone, The bid is for the creation of an E-commerce solution for a Custom Shirt Design factory. Generally speaking, it is a normal site with sales functions (shopping cart, payment via credit card [paypal is not needed] etc) except for one functionality I will explain later. First of all, I don´t want the desing to be OsCommerce-ish. Some Web 2.0 style would be a good choice. Here´s the kind of website I´d like to have. The design could be actually the same, with some small changes: [login to view URL] I specially like the design and some AJAX functions integrated to the website, like photo-zomming, etc. The categories in the website would be pretty much the same. Ties, Socks, Cuff links.. But here´s the great deal about this website: go to the "Design your shirt" section. This is where this website is different from other Custom Shirt Design sites I really would like to have something similar to this "Shirtdesigner v2.0". Whenever the visitor chooses design options on the left menu, the picture on the right shows him a preview of his new custom shirt. I know that developing this application has to do with 3D modelling and it could take too much time. But I also know that there are some softwares in the fashion industry that can generate 3D images from 2D drawings, and I think that might be the solution. Do you have any other ideas? I would prefer it not to be in Flash, but if you think you could do that so that it would run OK, that´s fine. I am also opened to other suggestions about how to develop a nice custom shirt design solution, just have on mind that Shirtdesigner v2.0 seems to be the best to me. Have you done something similar in the past? Please tell me if you have experience in such solutions. You will need to include in your reply in details what you will be doing with scope of work, please dont send us generic messages or replies. I will be working with you on the details before you start the work
