Are you looking to open a business that offers an endless stream of repeat customers, has a flexible work schedule, and allows you to make as much money as you are willing to put into it? If the answer is yes, then perhaps the car detailing business is for you. The average price for a complete car detail is $150 to $300. Even if you only service two cars per day, this can add up to a lot of money fast. Starting a detailing business may seem as easy as buying a sponge and a hose, but if you do not carefully plan every detail, you may find yourself in over your head before you ever make a profit.
