If you check with the city officials where you want to be operating your business, they will be able to give you the answers to what you will need. If you were to be operating out of some kind of store front, you would undoubtable need to fulfill much more requirements than if you operate out of your own home.
One of the things that I do for a living is that I am a house painter. Where I live, I do not need a permit or license to operate. Painting the inside or outside of a home or office does not require a license or permit. Of course I have liability insurance. I also have no employees.
I do extensive advertising on the Internet as well as the Yellow pages of the phone book. Most of my business comes from people who find me online. I also advertise with small advertising shingles that I place in various places. For examples of free sites to advertise on, and ways to advertise, please see the following links.
