I've used http://pickydomains.com http://pickydomains.com a few times. You pay $50 and provide information on what you're looking for (names you like, etc.). They brainstorm names. If they find one you like, they keep the money. Otherwise, they refund it. We used them when brainstorming Tumblon (http://tumblon.com http://tumblon.com) and Zencoder (http://zencoder.tv http://zencoder.tv). In both cases, they didn't come up with the final name we used, but they came close and gave us some inspiration for our final name. Most of the suggestions aren't any good, but when you get 100+ suggestions, a few are usually worthwhile.
