Check with your state development department and local/state health departments on regulations and health issues. Spas are like hair salons and need to be licensed and inspected. You might want to visit some local salons and see what they offer and talk to the owners. You will also have to hire licensed masseurs, facial and pedicure specialists. You will need to know the workman's comp and hiring regulations in your state and you will need insurance. A good business plan is a start. Contact SCORE for help. (score.org)
