Barter Website & Site Duplication

National company needs developer for a Bartering website. The site would allow members to barter items for other items from other members. Ex; one member has a bike, another member has a stereo, and they barter those items. A free and paid membership sign up required, member accounts, member barter history, barter friends, and maybe a barter rating system. A concept would be a cross between an auction site and a social networking site. Site will also need to be able to be replicated as a software product to be offered to people who want their own barter site. CSS style sheets with approx. five designs to start. Search capabilities by barter item category, by state, by city.
