Neutering costs vary, depending on a lot of things, including but not limited to Experience, equipement, location, preference of method by the vet.
I'm also in fla. In a 3 hour radious from me neuters are $78.00 in lakeland for traditional pom on, starting at $700.00 in Tampa not even sure what method they do because the cost was so outrageous I was dumbfounded. $45.00 somewhere near springhill for lazer pom off $70 something in Fortmyers lazer pom off.
Sometimes vet charge so much simply because they don't want to do them and if their rates are high enough people will go elsewhere whether that is because of lack of experience with neuters or previous complications for neuters I don't know.
Sometimes they are trying to recoup the cost of the equipement. I have a fantastic local vet that doesn't do neuters at all because their office won't approve spending the money on the lazer equipement ( runs around 30 grand I think )
It would certainly be nice if neuters averaged the same price accross the country like dogs n cats, that isn't likely to happen any time soon though. Sure would have a lot less back yard breeding and inbreeding if neuters were more affordable.
My advice for the OP, go on facebook, ask around in some groups for vet references in your area or however far your willing to drive
