Brutally Abused and Left For Dead!

I found her in the parking lot of the golf course literally taking her last breaths-a few seconds apart.  Got her breathing, and got some water in her and she started perking up a bit.   3 of her litte ribs are sheared apart and "bent" around the shape of a golf club on her abdomen, and her belly looks to have a serious herniwhich has now expanded allowing her intestines to ease down into her leg!   She was vey anemicand pale.  Due to extent of injuries,  I decided to see if she would fight for her life-and she HAS!!  She only weighed one pound when I found her, and was skin and bones-but if she is fighting this hard, I have to fight with her!  She has doubled her weight, but we cannot do any surgery to repair the hernia until her ribs have grown together.  That should take about 3 weeks. So I am begging for help to save this brave kitten whose first experience with a person (she was feral) was to get WHACKED with a golf club!!  And who became such a love bug and cuddler only 24 hrs after this horrific ordeal!!  (She was actually cuddling with me about 6 hours afterward-that night while I was trying to get her food and fluids down!)  I have taken her to the vet, we have taken x-rays which show the intestines outside of the body wall, under the skin-the hernia has grown now to allow her intestines down to her knee.   Surgery will run about $900 to $2000, plus the next visit which will be at least $250  to re-xray her abdomen , ensure the ribs are healing enough for surgery and do bloodwork.  
Any assistance would be GREATLY appreciated!!  Thank you for reading, and please share if you will!
