Design Lad for printing website

I am opening a new site very similar to cafe press. I need a design lab like customink but with many other features. First, the site needs to have all the normal shopping cart features, taxes, shipping etc... The design lab should allow a user to take whatever product they choose, move it to the lab and from there add a logo of ours or upload thier own apply it and freely move it to the spot of choice. the ability to flip the shirt or what ever piece and add a logo to the backside. If text is choosen, I would like them to have the ability to choose fontface, size, arc..etc. Thats a quick rundown of the design area. Also I want to allow users to open their own storefront. The site will be geared towrds the adult amateur industry so that being said I need the script to allow a person to open a store of their own based on a template. Their options. I will have set pricing and the markup from there. I want them to have the ability to upload thier own graphics and name the graphic.... Example A member of an amateur site wants a shirt with the girls autograph on it, he can go into her store, choose the shirt, add the autograph....etc. When he buys it she will get paid via the billing/affiliate program whatever her markup is. She needs to be able to have a wishlist, Items she wants so her members could go as far as to customize a nitie he wants to see her in... Many other features i want inplemented. I have hired one person and its been 3 months, he has been paid so i feel basically screwed. I need this as fast as possible.
