Took advantage of unpaid interns and relied on them to do prospecting for new clients and recruiting for new agents with no form of compensation or reward for success.
No upper limit on how much you can make. If you can somehow convince the owner of the company to sit down with you and your mentor and sell them insurance you get a cut.
Cons
You don't get paid unless you close deals. Have to pay out of pocket for almost all costs. Vast majority of people are not interested in insurance.
