Hey! I live on Long Island and because I have two females Im unsure how much a neuter would cost but maybe if you havent already you can try Island Exotics, it's in Huntington Station. When I went for my gliders toe amputation it was extremely expensive, and to be honest with you I feel they took advantage of me because I was 19 at the time. So make sure you pay close attention to what they're suggesting.
I say if you find one that will do it for $250-$300 then bite the bullet because LI is relatively costly. Anyways, you get what you pay for so again, you might just want to save up :)
