How Do I Start My Own Home Business, Teaching Cooking?

I have great culinary knowledge and I am going to school for food service management. I can’t find a good job because I need a lot of flexibility right now while i’m in school. So I am thinking of starting my own business out of home by appointment only. This business would include me meeting with the client to show examples of food menus and meals with prices, teaching (at the client’s home, in their kitchen) how to cook certain meals, possibly cooking meals for clients at their homes for small dinner parties or for their family. I already have a servesafe certificate, am a certified food handler in Los Angeles County where I will be working. What business licenses would i have to get and what else would i have to do to get this thing started?
