A good question to ask is what tools do you have available to you already?
you could make quite a few jigs your self just do a search on the o'l Youtube to get some idea of how to build them. If you're looking for cheap alternatives check amazon you can get pretty cheap parts on there, they may not be the best quality but at least you're not spending an arm and a leg to get your first guitar done.
As for wood there are some different options check local lumber store or hardwood store depending where you're located. My local Menard's gets figured timbers in quite often so i always go there and rummage through what they have. Take a look at my "home depot challenge" thread for an example. Another option is join some of the guitar building groups on face book often times you'll see builders that have an over supply of timber that theyll sell off pretty cheap.
This group has a lot of wonderful knowledge! and welcome to this expensive and addictive hobby! ( you cant build JUST ONE)
