All you really need to find is someone with a welder or tig rig and plasma cutter.
Anyone who has a race car, farm, rebuilds antique cars, etc will be able to point you to someone that can do it for you. If you are lucky it might only cost you some homebrew. Since you are in Marietta do you have a friend/acquaintance that works at Lockheed, I guarantee they can point to you to someone with the skills and equipment at home.
If you collect your parts most welding shops will do it for you, if you can't find someone.
