Hey guys and gals

I am a long time lurker, posted a few times, and I've about decided to take the plunge and look into starting my own shop. I have decided that it will be more than a hobby, since I don't see my personal situation affording me the finances to do it as a hobby. I am looking at getting with my local Small Business Association and taking out a SBA loan. I was thinking about getting enough for 2 or 3 small new CNC mills (or larger used machines) and maybe 1 or 2 small CNC lathes, plus all of the other associated machinery (cutoff saw, drill press, finishing equipment, etc). My thoughts are to begin making hardware for muzzleloading rifles (my father has made them from scratch for years) and looking for work to bid on from bigger shops that need help. I have worked in manufacturing for the last 28 years, and would probably work alone for a while.
Does anyone have experience with the SBA? How did it go?

Your thoughts are greatly appreciated.

Lyle
