House hunting

Ok so we are looking to move and well you know you forget that other people don't like pets in their places.  Though not all hope is lost, but i am getting a little down.  So now I am contemplating how to reduce my one small room for both of us.  Bunk beds here we come. Lol.

Any recommended sites? Any one know of someone looking to rent a two bed room place to a very responsible single mom with a 6 year old and a cat?

Thanks!
