This has got to be unbearable, especially right after losing your home. I agree about contacting his breeder --this is a REAL emergency, not just "you changed your mind" kind of deal, It would be great if she could just take him back till you are on your feet.
I know Sherman's breeder promised us that he would have a home with them forever, should the need arise. I think most breeders feel that way. You are in our prayers.
