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

Any name not already used in a .com web site name is probably not trademarked.

It's a good idea for a smaller operator to use a domain name that describes the subject of the site.
