I'm 19, I'm located in LA.I been doing automotive detailing for three or four years now. I started when I was 15 with my father.(It was a father son thing). I been mostly detailing family and friend's vehicles. I was charging $100-200 for full service back then. It's going to be higher when I open up. Now I want to expand my detailing skills to a new level. By that I mean opening a small detailing shop, i'll be working by myself for a while to get a feel for how the business field works. I already have a 6000sq ft garage shop. My grand father bought it out for his small business In 2006. Now that he's retired he doesn't need the space anymore. The major question here is, how do I go about opening a shop? Do I need to obtain permits, businesses license,etc to open up?
