Look at this link... www.utahpets.org/fix/bigfix.htm
They are offering discounted neutering... only $15 which is a really good price I think. It's provided by the Humane Society too!! The locations are in Utah and Davis Counties however... you may need to call and find one in Salt Lake county.. or I may be able to help you get your little one to get the snip!
I read your previous post about your bf not wanting you to get him neutered and he is WRONG!!! First of all, what happens if you break up.. (not saying you will, but that is always a possibility).. who will take the cats, feed them, and pay to care for them? That is definately something to think about! Tell him that!
Anyway, I've gotta run.. work is OVER!! yay! Let me know if I can help.. You know I'm only 40 minutes away!
