That is a very good strategy for busy professionals and car owners who will most times find it difficult to take their cars for detailed care,one can go a step further to set up a sit and notify persons that would need these services.What would you think about a car detailing business that provides door to door.detailing services that are targeted to people who are too busy to be able to take their cars to a designated detailer. And is that a good option for a business idea on a small scale which i can allow my little bro whose 20 to start. .?
