I think I know what you mean. I've done various kinds of metalwork for around 20 yrs, day job of also doing all kinds of metal/mechanical work always remains necessary to keep going, and time's limited to do creative stuff that I can't figger how to make enough money on. However am getting enough interest in my products that I've decided to form an LLC. Turning my side work into a separate business entity is new to me and although I'm reading some about it, I'm interested in trying to learn something from others here who have done it successfully. Where and what kind of insurance do most people get in this business, what sort of stuff do most people put in contracts, etc., etc.
