When I first started out. I set up a E-Commerce store with the Domain name company that I purchased my domain name from. (godaddy.com) They offer a store front for a small fee and you can sell directly from them. You would have to set up your products but they give you a very easy to setup and maintain system to do so. I don't know of any wholesalers that offer a store except one. It is called International Wholesale and Drop Shippers Corp.

They offer means of setting up a store as well at the bottom of there task bar on the left side of there website. You can check that one as well. I don't know if it uses there stuff or if you can or have to put in some of your own. Let us know how you make out.
