The thing is if it's a good domain name it's probably been taken already. In the past, when I was trying to find a domain name for one of my new projects, I'd sometimes spend hours searching for one. You can try Yahoo Small Business to see what is avaialble. Where it says Get a domain you can check domain name availability. Just spend some time trying different creative ideas, you may stumble onto something that sounds great and is still available: http://smallbusiness.yahoo.com/
