Replying to Lawn Care Thread

no this is not a joke or ironic. My equipment consists of a Husqvarna HU 725AWD mower, a Black and Decker electric trimmer, as well as a Black and Decker electric edge hog. I mow lawns for a multitude of people around my neightborhood, but i wanted to ask a few questions. What are the necessary steps to make my business official, and is it even worth it? If I should consider this, what are the recommended tools that I should have in my quiver? (specifically commercial)
Thanks.
