165537 Multi Seller Ecommerce

Hi, I need a complete site build, which can hold mulitple sellers. Basically, the setup is much like Amazon, a site where sellers can upload their products, into certain categories, and then sell them to the site's visitors. When a seller wants to upload a product they must be able to choose a heading from a dropdown list and also choose sub catergories, much like eBay. They then must be able to add details, just like eBay, Condition (dropdown), Description etc. They should also be able to upload photos. They should be able to enter the price and the quantity and the delivery time and price (which will appear as a dropdown to the customer). There must be an option for me to charge the sellers per transaction, and to change the price, as initially I won't charge for the service. The customer must be able to have a account such as with Amazon or eBay, with the applications of both, such as a 'wishlist', items bought, favourite seaches, favourite sellers and an ability to rate the seller once their transaction has been processed. They must be able to search for products, or procede through categories to find the product they want. The homepage layout must be customisable by me, I have a decent understanding of html, and can learn some new stuff if needed. The site must be well designed, and well optimised for the products. The URL for the categories and products must be such as Amazon: [login to view URL] for example. The payment must be all routed to me, through a well proven payment method. Any questions please ask. This need to be a very well designed and optimised site. No time wasters please. Many Thanks, SKM
