Surgery For Found Cat

Last week I posted about a cat that was out back of my house.  No one has claimed the cat and my neighbor was kind enough to bring her in from the cold .  She discovered she had issues with her mouth and after taking her to the vet she found out she has a fractured jaw in two places with exposed bone.  The fracture is pushing one of her lower molars so it connects to the top tooth and she can't fully open her mouth.  The vet said this type of trauma is caused by a severe fall from maybe a window or moving car.  She is chipped but the information is out of date.  Ultimately we want to find her a good home but in the meantime want to get her healed.  We thought she was young but from the chip found out she is about 9 years old.  She is such a sweet cat and just wants to be loved.  I am asking if you can help with the cost of the surgery.  This isn't something we were expecting but want to do what is best for her.  Anything you can contribute would be appreciated.
