Well first off, Im a 20 yr old full time college student and this season will be my 4th yr in the green industries. I have my business license but that is all. I am needing to know what other legalities I need to have to do the work I offer. Basically I mow 40 res. accounts, trim hedges, and minor installs. I have a truck, trailer, two exmarks, and all the handheld goodies. If asked I will do other things like cut trees, trim trees, pressure wash, etc... I was wondering if there would be anything else needed to be official in TN. And what kind of insurance policies to get and so forth. Any advice would be very appreciated.
