I found as much information as I could for your state and posted it below; at the end of each bit of information is the link for the page I got it from. That is way too high, do not pay that, that vet is going on vacation paid for by you.
If by chance you need more you can respond back here or I can be emailed at this site, I hope it was helpful to you in some way. Sorry guy for the long post
Spay/Neuter Assistance Program
Our Spay/Neuter Assistance Program (SNAP) provides financial aid and advice to Placer County pet owners who need help. The program is funded by the generosity of donors to the program and by grants aimed at bringing an end to pet overpopulation. If you are in need of spay/neuter assistance for your cat or dog, please call our shelter at: (916) 782-SPCA (7722) ext. 201

Programs that provide low cost or free spay/neuter for cats, listed by state. Some programs work only with pets of people with low incomes. Some do not consider income but serve only pet cats -- or only feral (untame) cats. But other programs serve all kinds of people and cats. We believe the listing details below are correct at this writing, but call the program to be sure.

Spay & Neuter Information
One unspayed dog and her offspring can produce 67,000 puppies in six years! Many of these puppies are abandoned, allowed to roam the streets to continue the breeding cycle. Others are left at already overcrowded shelters. Nationally, only 25% of dogs at shelters are adopted. In California, over 250,000 dogs are euthanized each year. Spaying/neutering is a vital step in combating the issue of animal overpopulation and euthanasia.
There are other good reasons for spaying or neutering your dog(s):
1. Prevents prostate and testicular cancer in your male dog.
2. Reduces the rate of uterine and breast cancer (in *****es) when done before the first or second estrus cycle.
3. Prevents Pyometra, a potentially fatal infection of the uterus in female dogs.
4. Reduces inter-male aggression.
5. Reduces dominance aggression towards people.
6. Reduces roaming.
7. Reduces “mounting” behavior and sexual frustration.
