Saving Ziba after car accident

Decided to take a road trip up to to see my parents for the holidays, and not even 45 minutes from home on the highway, we were rear ended by a police sheriff which caused a domino effect which involved 5 cars total. My 4 year old Husky/Rottweiler was injured due to being in the backseat. Headed to the part where we finally get to the vet, we learned she has a broken front leg which is located right by the joint. Now she will need to have surgery in the next week in order to get screws and have everything set but like everything animal related, money first. We have paid her emergency vet of $1200 and I don't have enough money saved to put together $3500 for her surgery in a week. I truly hate to ask anyone for their money because we all need it, but I need my baby to walk. Anything and everything helps. My dog is my world and it kills me to see her in any type of pain.
