Where can we get our kitten "fixed"?

We just rescued the cutest male kitten. He and his siblings were found under a dumpster. He hasn't gone to the vet yet, we are planning on taking him soon. Money is really...really tight for us. I dont expect anything free but, is there a place you can get your pets checked out and neutered for a lower cost then a vet. With our financial situation, now wasn't an ideal time to get a pet,...my family really wanted one, he was free and needed a good loving home.
