It may be quite a challenge to make such a business a success, gaining the critical mass for it to take off may be the most difficult part, song significant advertising budget may be required.

One seeding idea, at first make the main function of the site a directory of items for sale on other sites like Ebay, the breathe volume of content you might be able to generate would help gain search ranking and site authority, you can then start redirecting people to your own buy/sell section.

You might search for Ebay Clone to find pre-written site scripts.

There are sites with tools that help you come up with fictitious names, including: wordlab.com, naming.net, wordoid.com, lingzini.com, namestation.com, domainsBot.com some of these tools look up the domain name availability as you go.

If you find an available .com name, there's a high probability that it' not a trademarked name.

(something)market.com ? (something)online.com? (something)shop.com ?

you could put part of your name in it like your first name, or surname, just because many names may be taken already, so you'll need something unique to make sure no one has that domain name yet.
