Wow, thank you so much!! I contacted them to make an appointment.Hi! I don't live in Phoenix but I dug around and there is a place that does rabbit neutering for $150.
Here is the link if you want to check it out - Veterinary Services in Phoenix
Now, you may be able to find a price cheaper than that, but this was all I could find for now.
If you scroll down on that page, it will show a picture of a rabbit and the costs!
