Three more points:
1) No one is coming to your shop to see your tattoos. Your tattoos aren't your product/service, the guns are. Don't ask for or allow your body art to be an issue at all -- 90% of your clientele is going to ignore it, or at least overlook it if you have a service and/or products that people want and you treat people as a business owner and
salesman should. The other 10% were lost to you the moment you put the needle in your skin, so there's no point to worrying about them now.
2) You are entering a
service industry -- even if most of your profits come from sales, brick-and-mortar stores run on service these days. If you don't feel like a humble servant of anyone and everyone who enters your door, doing whatever it takes to get them to give you their money -- you'd better learn to act like you do.
Life in small business is TOUGH. After not much time at all trying to keep the lights on, you'll find that all the individualist, "I-gotta-be-me," [SINATRA]"I did it MYYYYYY way!"[/SINATRA] stuff is a vague memory, lost in a flurry of "Yes, sir," and "No, ma'am," and "I'm sorry, sir," and "I'll stay late to fix your problem," and "what else can I do to make you a happy customer?" -- and so
very on, and so
very forth.
3) In the face of a zillion competitors on-line, and probably a dozen in any region of the "real" world, the biggest product/service you're selling is
YOU. Trust in your skills. Faith in your recommendations. Approval of your artistic eye as a 'smith. And appreciation of your sales manner. ANYTHING that makes YOU less saleable, needs to be minimized. Whether or not your body art makes you less saleable depends a bit on what & how far out of the local "mainstream" it may be, and a lot on how self-consciously you deal with it.
