Private licensing is good. It is one way in which a free market provides quality control.
But people should stil be free to work even without a private license if they can find customers. With my money I should be able to hire anyone I want to to do my plumbing!
And this guy has been in buisiness for 5 years and has saved enough money that he is considering buying a company for 250,000. That tells me he isn`t strapped for customers and must be good at his job. I`d hire him.
