You would probably have more luck with the biz license bureau in your area. Around here, they don't like people operating unlicensed businesses bc they don't get their tax $$$$. That said, I wouldn't fool with what I think you might call "fly by night" lawn cutters. Elevate yourself above all of that and put your time and energy into making your own biz thrive. Then you won't have time to give them a second thought.
Also, in our area, there are a lot of companies that don't advertise on their vehicles for various reasons. We don't do it. But any vehicle used for commercial use is supposed to have a DOT number, medical card and all Of the safety equipment. The DOT stops people around here ALL THE TIME!
One more note...I am in total agreement with the comment ab not depending on the government to do anything to help the small business. We Do make this country thrive. We DO pay more than our fair share in taxes. It sucks. But I would still rather own my own business than work for someone else.
God Bless!
