Help me get out of homelessness and move into a new place

I recently moved back to Nashville for the second time after being in Florida for 9 months and I've been homeless since I got here. I have a full-time job and I don't do drugs or alcohol but with the economy the way it is it's been really hard to get on my feet. I was able to find a small apartment through Facebook and it would only cost $650 to move in. Any help would be appreciated.
