apparel customization by costumer - open to bidding

Iam looking to set-up a new website like a [login to view URL] and tailorstore.com. Here's what I have been looking for (explained as lucidly as possible) - 1. Front end ([login to view URL]) 2. New store owner registration + sub-domain for user ([login to view URL] or [login to view URL]) 3. Store customisation ability for store owner(nothing fancy - store owner can add banner, logo, change colors etc.) 4. buyer can select product, fabric material, and techical design 5 Store owner can display a number of product images on his store (items for sale) and the sale can be made straight from the store-owner's subdomain. 6. Buyer login etc. 7. Database that maintains buyer information etc. 8. Some sort of system where the store owners do not have to re-register as buyers when they are shopping for products at other stores and similarly - the buyer doesn't have to re-register as seller when he wishes to open a store of his own. 9. Back-end support - tracking orders/ administrative view for the admin to see what store-owner has been doing what kind of business, what commissions need to be paid out to whom etc. 10. Any other critical idea that I missed. . We will be giving out commissions to store owners via check and need everything to be on order with complete back-end for the admin.
