Help Snowflake beat pyrometra

My little baby girl Snowflake is 6 years old, in a very loving family. I've tried and called so many different vets offices to see who can help but it doesn't seem like anyone can help. I found out she has pyrometra which is an infection in her uterus. It's life threatening and needs to be taken care of asap. I was told by the ospca that I have 3 options. Get the surgery, surrender her to them or put her down. Only 1 of those options I am willing to accept. Get the surgery. But I can't do this alone. I'm hoping someone out there sees this and has the heart to help me do this.
