The county thing (at least for the state, not talking about a carrier) is only for an office in FL or where you're physically meeting with clients.The license is perpetual, but I guess it's an "appointment" fee that I'm speaking about.
It's $6 per county, but somehow UHC charges me $300 year for the whole state.

Not saying you're wrong, but I've been non-res (phone only) in FL for over a decade and it's one of the few states that doesn't steal from me every year or two with dumb fees.
