I would suggest you contact Christian Guardione at ww.newtravelservices.net.
My family contacted a number of companies in Sicily for our vacation last year and Christian's companies prices were better than almost every other company. He picked us up at Taorminia airport, drove us to Etna, he picked us up for our trip to the Aeolian Islands and we toured Savoca and Taormina with his company. Christian, his father and other relatives run the service and are punctual and nothing is ever a bother for them. Very nice cars and vans. Read the reviews about this company on tripadvisor, you won't be dissapointed. Hope this helps
