I run my business out of a suv and 4 x 4 habor freight trailer. I am doing very well considering I have around 3k in equipment and have made considerably more than that.
I tried getting prices from other companies and having them do jobs for me, but honestly, there is a serious lack of pressure washers in my area. All it is going to take is one serious person to build a business to dominate the area.
Learning lots here though
