Drivers in Chiusi / San Casciano

Hi - we're a couple of adult non-drivers looking for someone to take us from Chiusi to a farm in San Casciano and then work as someone who can take us in and out of SC on a day to day basis from around 25th July to 4th August (could be from 28th July til 8th August though).

Where / who is best? Not bothered about just hiring someone local who can help out, btw. Would like to know rates and the kind of car they have too.

Thank you.
