private car service

Hi Elena,
It is wonderful to find your site which is like an SOS avenue for first time travelers to Italy like us. We are a group of four in our 60s and we wish to spend about 5 days in Tuscany after Rome. We do not wish to drive and would like to know how to engage local folks with cars who may wish to take us around. Please advise us the estimate cost per day for such service.
We also appreciate your recommendation where should we be based and which are the areas to tour around for 5 days stay.
Thanks and best regards,
Vivien
