Startup a car wash and detailing business. Make flyers to put in people’s mailboxes with prices and a description of what you do. Do research in local companies who wash and detail cars so you can have competitive prices. For washing the outside all you need is a bucket, car soap, car paint safe sponges (1 for the car and 1 for the wheel hub caps), and a hose. If you want to add detailing to it then you will need window wash, a microfiber rag for the window (newspaper is good for getting streaks out!), leather wipes for conditioning leather seats, a vacuum, maybe rug shampoo for the floors and cloth seats, and armor all cleaning wipes for the dashboard and doors.
