Agree, its quite a project if you haven't done this sort of thing before. You'll probably spend as much buying the correct materials to do it properly as you will just paying a shop to do it for you. You'll end up buying quarts and gallons of things that you will only use a little bit of.
Of course I started out doing the same thing and it turned into a carreer for me for a few years, so it depends what your intentions are. If you are just trying to save money you probably won't. If you are doing it for the experience then it will be worth it, but take your time and use the proper materials and be careful. You don't want to hurt yourself or overspray the neighbor'* new Cadillac.
I've painted more cars and parts of cars than I can count or remember. It can be fun and it can be disappointing. Make sure you know what you're going to do before you start. Half finished projects are a drag.
