open the phone book or yellowpages online. There is a a place here outside of DC that sells seed. Cheapest would be Brown Top Millet or Rye IMO, but im not sure. It will grow fast to fill in the bare spots and you can re-seed over it with Bahia as you see fit. I think its about $50 for a 50 or 100lb bag. cant remember the bag size. Here ya go
