Fayetteville NC labor

I’m interested in buying the equipment to start a small soft wash/power wash business. I’m doing this for my sons 13 and 14 so that in a couple of years they will be able to hopefully work their way through high school, college, and gain valuable business experience. I would like to offer free labor to some one around the Fayetteville NC area so that I can pass on the knowledge and experience to my sons. As I am active duty I would only be available on the weekends. Thank you in advance
