Looking for a Logo

How does one go about getting a logo made? I’ve gotten a couple of tentative offers, some concepts, and a few ridiculous quotes, but no one seems to do real logo work anymore. I’ve got two people promising drawings, but I haven’t actually seen anything yet.

Does anyone have recommendations for me? I’d really like to see some concept drawings of a nerdy superheroine. Comment on this post if you’re interested; you can use your Facebook login to do so.
