Baby Kittens

I love cats. I have several cat colonies that me and my girlfriend feed. Recently we've started rescuing and fostering the kittens from our colonies. We currently have 10 kittens here with us from 3 differen liters as well as 2 out with a foster. My vet will neuter the 4 boys for $55 each = $220 and spay the 4 girls for $75 each = 300. The spay/neuter equals $520. However, we have 1 beautiful boy who got crushed by the couch on accident when I lifted the couch to get the kittens out from under. The emergency vet is trying to charge us $5000 dollars to set his baby kitten jaw. Why that is I do not know. Anything will help these babies. I have 5 cats already. I need to get these babies spayed/neutered and adopted out to loving homes. Ive found multiple kittens that have had ridiculous eye infections who were left for dead. I love watching those get big and fat. Lol Please help
