In NC there is retail and wholesale. You have to have like 100 square ft of office space that is not connected to another business, meaning its own external door ways, zoned commercial, and have operation hours between 8 and 5 for inspection. If you miss being inspected like 3 times then you can lose your license. So renting a room from someone is out. Then you have to have a million dollar insurance policy. Pretty much shot my ideas down.
