While I appreciae the warning about this service, and would certainly look up on line reviews before I booked, I have to question why the owner's hiring practices are of any concern. I think the driver's lack of professionalism is more alarming. You've also contradicted yourself...If they are employed as sub-contactors, there's no expectation that there will be work next week, and no health insurance. It seems that your claims against the owner, if unfounded leave you open for slander charges. And this website has no obligation to protect your identity.
As a former DOT employee, I would hope that you wrote a letter to the FL DOT, and din't just choose to cross the internet with first-time posts on multiple message boards.
