Design Inventory Web Site

I am looking for a website that shows and sells some cloth products. Below are the functionality I am looking for. 1) Admin user? need to be able to add new products with their images and decide which menu/category it should go under and put the prices? for the products. 2) Normal user need to be able to register on the site, search/select the required products. 3)? Normal user need to be able to place the order and be able to do online payment (shopping cart and checkout).? Need to provide ability to enter optional custom specifications before placing the order. 4) The order? needs to be emailed in a particular format to the admin. More details can be discussed. Thanks,
