Tried contacting them to get an idea of their prices but no response yet.

Well you wouldn't have to rent a car but since these most of these are 9-7 and include pickup and drop off, probably will end up being pricey.

try www.sunflower-tours.com - Giovanni Sirabella - he's a nice guy.

And what are their prices like? You wonder if they won't publish the fares.

Looks like rather than have specific tours, they have an open-ended, "where do you want to go" kind of livery service.

If you haven't gotten a response, or even if you have, try www.hillsandroads.com. Luca Garrapa will take excellent care of you, if he is available. Dave

Well the Verbena Blu agency replied and said some of their tours are in the range of 180 euro per day. They are booked throughout May.

But I believe these prices are for minimum of two people since they are presumably using a sedan. So it would be more in the range of 360 euro.

For Cortona, it might not be bad because some car rentals would approach $200. But this tour is guided with lunch included.
