How to promote door-to-door car wash services?

Hello! First of all, I once wanted to open a car wash like this in my spare time at work and hire a few workers to wash the cars, but I never thought about it. I didn’t have much money and I was afraid that I would be too worried and have no business. So I just put my Let me share my ideas with my brothers and let’s study together. First of all, the appointment format is not good and car owners will find it troublesome. The prices are almost the same. If I want to have my car washed, I have to make an appointment. If I want to have my car washed, I can just drive there and have it washed, or you can come to your door as soon as I give you a call. Don’t make an appointment, but you said that the labor cost is high if you just call and go there, then you should study how to reduce the cost. It doesn’t feel good to make an appointment! Second, I don’t think it should be free. Everyone is afraid of it. The more enthusiastic you are, the more worried they will be. Third, you should find a good car. For cheap cars, they won’t even wash them at your door or even go to a car dealership, because they just If you don’t want to wash your car, just get a bucket of water and do it yourself. If you can spend money to go to a car dealership once or twice a year, it’s good! And when you go to the car wash, how do you get there? Driving a car with equipment and workers? Then when you get to where the car is parked, you wash the car there, right? The car owner just stood aside and watched or waited. He didn't look and felt uneasy, but when he looked around, everyone in the neighborhood knew him and was more conspicuous, so he felt that he was not low-key enough and was losing face, so he was unwilling to come to the door to wash. I I just analyze it this way, because I think this project is very good. The problem is that you have to grasp the psychology of consumers. Think about it! Let’s communicate later. You’d better tell me your QQ. We can chat on QQ in the future
