I just recently went through this as well just take note I am located in MA so I do not know if it is the same where you are located.
I found out that I needed commercial plates in order to conduct business as a landscaper in MA so that commenced my search to find plates. I was told by two insurance companies that I would be OK with a personal policy including something called a "class-30" which is a business use class on my insurance policy however, I decided to go with a full commercial policy just to make sure I am fully covered no matter what.
Business liability insurance is also a great idea. I have heard people say they would not step on to a property without it.
Hope this helps,
1 Cor 13:13 And now these three remain: faith, hope and love. But the greatest of these is love.
