Vet Bill for Levi the Anaconda

Levi is my pet green anaconda I have had 9 years since he was a baby. He always had no issues eating but he hasn't eaten in over 8 months now, and there's a growth on his tail. I took him to the only nearby vet that would even look at a snake and was given a 1600 estimate. The vet is worried that this growth is causing him pain, and therefore making him disinterested in food, and when removed he might start eating again. Surgery is scheduled for May 23rd, and after surgery, the full amount will be due and I cannot afford it in such a short time frame. I'm begging for help, any help you can provide so I can save Levi.
