I'm former military; and a Computer Science major. (Still can't find a job right now.) -- The gunsmithing is a intriguing, maybe I ought to learn that.
Gusmithing has been my hobby for years, and it may very well become my primary source of income soon.
Not enough gunsmiths in America, and way too many people with guns they have no clue on how to repair much less clean.
Even a simple cleaning service like a monthly plan for a fee gives you weekly cleaning and maintenance, even at your own home.
Like a Stanley Teamer service except it is a service to maintain your weapons by trained professionals. So many people live in diverse areas, even lubricants are important if you live in AZ or AK.
Thats my business plan, an at home tunup, service and firearm cleaning package availabe for a monthly charge.
