Starting a detailing business is expensive, you have to get all the legal stuff done which is going to run you at least $1000 and then you have equipment costs which will run at least $5000 providing you want to use decent chemicals and tools. You also have to account for time, anyone you want to hire, insurance, taxes on the money you make, transportation costs, utilities bills, rent on a shop or payments on your truck if you are mobile. I'd say to start out I spent a total 12k, it took about 3 months to even it out, but now it is a great investment. It probably won't be a business that makes you rich however, detailing is dependent on too many factors; weather, economy, other people's schedules, etc.
If you hit gold and get the right contracts though, it can be very rewarding, and you can make money doing something you like.
