Private driver, Florence to Casali di Bibbiano Villa, Tuscany

I’m in Florence for a few days and wd like a driver to take me to Casali di Bibbiano, Tuscany, which is 90 minutes south. I don’t need them to stay w me. I’ll be there for the day and then need a driver to then return to Florence in the evening.
Any suggestions from a service you’ve used?
