Don't know what work mans comp in Florida is, it's around 14% in NJ.
Liability insurance $$$ ?
SS/Med, employee pays 7.5%, employer pays 7.5%, you will pay 15%
You only get mileage deduction for use during work, not back and forth to work. Tools, boots and other work related deductions you get as an employee, if you pay for them, no change there.
Good luck. Hope you don't spend lots of money setting up an LLC. Before crunching the real $$$$
