Paros and Naxos - Taxis/Drivers for Transportation?

We are traveling to Paros and Naxos at the end of September. We are at least going to rent a car for a day in Naxos to drive out to the villages/mountains, but for other days or occasions where we plan on drinking such as dinner or excursions, we’d prefer to have a driver. Does anybody have recommendations for taxi services? Based on our research so far the reviews on availability seem very mixed.

Thanks!
