The best way to compare limousine rental rates in Tampa Bay is to compare written totals for the same vehicle class, the same hours, and the same inclusions, because a headline hourly rate without those three facts is not a comparison at all. JetBlack does not operate in Tampa Bay, so no JetBlack fare is quoted here, and no Tampa rate should be borrowed from a New York price list.

The comparison that actually works
Ask every Tampa Bay operator for the same four items in writing: the vehicle class, not a specific make or model, the hourly rate and the minimum hours, the total for your trip including tolls, airport fees, gratuity, overtime, and cleaning or damage terms, and the cancellation rule. Then compare the totals, not the headline rates, because an operator with a lower hourly rate and a four-hour minimum, plus gratuity and fees added later, can cost more than an operator with a higher hourly rate and everything included.
Published Tampa Bay ranges are useful only as a sense check, and no single Tampa fare is quoted here, because rates vary by vehicle, by season, and by event weekend, and a single figure printed without a vehicle and a date would be wrong for most travellers. A quote that cannot name its vehicle class, its minimum, and its total in writing has not met the basic test for a limousine hire, whatever it calls itself.
What to watch for
Watch for a rate that excludes gratuity, tolls, or airport fees and adds them at the end, for a minimum that turns a two-hour trip into a four-hour bill, for overtime charged at a higher rate than the quoted rate, and for a vehicle substituted for a smaller class on the day. Confirm the vehicle, the hours, the total, and the pickup plan in the same confirmation, and keep that confirmation, because a written total is the one that governs on the day.
