Dog's Surgery Needed: Hematoma Spreading

Hey guys! I don't like to ask for help but when's there's nothing left that I can do, help is all I can ask for, no matter how small the donation is. My dog is like a son to me. He recently developed a large Hematoma in his right ear as you see in the picture. The vet says they have no choice but to into surgery which can cost up to $2000, which at the moment I do not have. He needs surgery asap, as it looks like it's going to his face as well. Thank you.
