Help with Skys surgery cost

Hello everyone, recently my Siberian Husky named Sky who is 5 years old and has suffered from Pyometra. It's basically a condition where the dog suffers from an infection in the vulva, and can cause death. Here is a more indepth look on wiki. https://en.wikipedia.org/wiki/Pyometra
Sky was rushed to the ER vet at around 11pm( on 8/19/2015) at night due to she was pouring blood all over the floor. She went in for imediate surgery. The vet said it was lucky we didn't wait, the infection could have popped at any moment and killed her.
Sadly this all happened the day after my birthday. We had no idea why she was in the condition she was, so we rushed her to the ER. There they descovered she had  Pyometra, she is still in the ER after the surgery. She is on pain medication and is not eating yet. The vet still wants to keep her to check her kidneys. So far the bill for the surgery alone is about 6000 dollars. Skys sisters Roxy(a German Shepherd) and Bear(Rottweiler/cane corso mix) both miss her very much and are pacing around without their oldest sister. She is my first dog and like my other dogs, I would do anything for them I can. Please help us if you can and if you can't please share with your friends/family. Thank you very much.
