Emergency Care for Bailey's Jaw

I normally hate asking for help but last night my dog, Bailey, was bitten by another larger dog while on a walk with my father last night. At first we didn't notice any injuries but after a while we noticed he was bleeding and his tooth was hanging outside of his mouth. We rushed him to the emergency vet and admitted him until monday for pain meds. The doctor said he has a fractured jaw, and about three broken teeth. The vet bill for just the hospital stay until Monday is over $4,500, with the surgery he needs for his jaw, it's an extra $7-13,000. Anything would help and no pressure, just trying to get my baby the best care possible.
