Help highway kitty fix fractured leg

Hello my name is Jessica and I'm currently a college student at UCF in the Orlando area. As I was driving to work 8am Wednesday morning, I was merging onto the highway of I-4 in Casselberry, FL, I noticed a halt in traffic due to this kitten in the middle of the road. I immediately put my car in emergency park and rescue this frighten kitten. Unfortunately, as I was driving I put her in my car in the middle of the highway, she crawled up inside the internal of my car air filter and got stuck up there. I was frighten to continue driving because I didn't know what compartment she was in and the heat of Florida was at one of its highest. After numerous attempts of calls for help and hours later, me and my friend, Katie, finally got two Casselberry officers to help us out and rescue her out of the tight space. Immediately after we took her to the nearest vet, and they told us she had a fractured leg and would need surgery if she wanted to be able to walk normally again. Currently her right leg is fractured but due to that she applies a lot of pressure onto the other leg causing it to deform overtime as well. Her other option was putting her in a splint but that won't guarantee that ability. Her best option is surgery. I've always seen unique story happen to others, this is mine. I really want her to have the best life and I want to give her that but I do need help. For those who can help, anything will help and would be greatly appreciated. Thank you
