I am looking to retire in the near future. Rather than give away what I make, I was thinking of selling some things at craft fairs to supplement my retirement and give me extra cash for TOOLS. But I do not know what I need as far as insurance, tax number or anything else. Do I form an LLC? What is a ball park figure on what it will cost me? Who do I contact for this information? I would really appreciate any help you could give me on the subject.
