ISO rescue to sponsor foster dog

I’ve been trying to save this dog for over a week. He has $600+ pledges on Instagram and I am willing to foster him indefinitely. He’s in Los Angeles and I have transportation to the SF Bag Area (where I live) lined up for Thursday the 20th. I have reached out to a dozen rescues and most of them won’t even respond to me… does anyone know of a rescue I can reach out to that might help save a shepherd/husky mix that is super depressed and living in a concrete cell the size of a crate with no window? I’m desperate – he’s due for euthanasia!! Feel free to PM me if you want to see his video. Leo A546299 at Moreno Valley Animal Shelter
