Help with Ginger's Vet Bills and Spaying

My partner and I found Ginger meowing outside 2 nights ago and she came into our laundry room very hungry. I checked the tag on her collar, and it had a number which we texted to find out if she was lost. The person on the other end implied their family moved out of the area and she might have been lost outside for the past 2 to 5 years, it wasn't really clear. We went to the veterinarian today and are waiting to hear back about testing done to see her FeLV / FIV status, but we did find out that she has not been spayed. This gofundme is really just if people want to help us with her vet bills. She's a very sweet cat and I'm hoping she's healthy otherwise but we do need to schedule to have her spayed. The exam, tests, and vaccines today came to $350 and they gave a rough estimate of $300 to spay her depending if she goes into heat etc. She's the cutest best little girl. We really appreciate everyone caring about her just as much as we do. The vet said she was a perfect patient and they wish all cats were as calm and sweet as her.
