In time you might want to think about offering reliability services such as bolt and hammer profiles and also port work. I have previously chosen a gunsmith who has paid attention to finish details such as riveting the trigger guard, welding up the trigger holes, and refinishing with duracoat. Then you can move onto 100 series folder installs. I know previous members who have started profitable business model's doing just that. In fact, one is working on my 040 as we speak. But I think the real key here is expanding your client base by offering rifle conversions as well.
Good luck, an
