Cool idea and I'm a big fan of the simple design. I have a friend here (Austin resident myself) who has been painfully vetting options this month through CL.

Looks like some of the filtering tools don't work -- I selected a min and max age of 23 and 30 respectively and the results shows people beyond that range. Screenshot: http://puu.sh/2lZ6m

I also think it would be a good idea to take a few pages out of Airbnb's book of how they handle reputation and let people link their Facebook account, as well as offer a background-checking service for people to help boost their marketability. A references function (like Linkedin) would also help.

Best of luck!
