Foster home or new home (Phoenix)

I have a 4-year-old mixed male dog I lost my place to live I need to find him a new home today or Foster home if you can foster him for a couple months I can afford to pay for his food and everything till I get back on my feet if not I need to rehome them and I need to do it by the end of the day tomorrow and I've run out of options I don't want to have them gas down at the dog pound
