You have at least three choices.
a) You can hire a local artist and wait for days (weeks) for the result, then pay quite a lot, perhaps, for the outcome. Or…
b) You can use 99Designs, pay about $300, wait only a week, and get some great suggestions.

or
c) You can use Designmatic and do it yourself, using their great tools.

We (Tina) recently needed a logo fast, used Designmatic, and — it worked great! (You might even try WRITING something for them. If you do that, you might still get it for free.)
