My husband, Matt, is really good at it and it's a great source of income, especially in between pond projects. And these jobs have a great profit margin, as there is very little material, mostly skill and labor.
Others have chosen holiday lighting, hardscaping, landscaping and even pools to complement their services.
The best part? If you have a good email list, you have a built-in potential customer base! I keep my helpful tips but then add in others things we do too.
