Ask YC: Best freelance dev exchange?

Where's the best place to post a freelance dev job and have people bid on it? Elance is the only one I've used before and with terrible results. (In case you're wondering, I'm looking for a Drupal/Wordpress MU bridge. Drupal's great for most CMSey things, but its multiuser blogging functionality stinks. I'd like a bridge to give me single login and the ability to call a user's profile info into their blog template and their blog info into their Drupal profile.)
