Thanks to all who responded. I am going to get some experience and learn everything I can just as I did with the automotive thing. I may actually do better at this than working on cars since I am interested in it. I will take almost everyones advice and just work for someone a while. Learns the ropes and see if I actually want to run my own business. I know this is what I want to do just dont know about running the whole show myself.
Thanks again and I will keep reading and will go get a couple of those (way to short to learn much)courses to get me in the door.
