Christine, Jen is absolutely correct. You may find males that fit your needs at that price, but look around....you won't see a breeding age female for anywhere near that low of a price, especially with the proper equipment to keep her in good enough health to be breeding.
My advice to you would be to start with a good healthy captive bred baby or 2, which you should be able to get in your price range....and grow him/her/them up. But make sure you have all of the enclosures set up properly before you get them, so you know that they will grow into healthy animals that will produce healthy babies. Learn all you can keeping them as pets before deciding to dive right into trying to breed. It's a lot more fun as well as rewarding that way.
