Chris,
Contact Tony McGann who lives in Doolin. We used him for several days of driving when we were in Ireland a few years ago. He was very reliable, reasonable, and has a great sense of humor.
He drove a large VW van that could seat 8, along with any luggage.
He actually took us to the Rock of Cashel the first day, after picking us up at the Shannon Airport with a few other stops along the way, before making our way to Kenmare for the first overnight. Then the next day we left for Dingle on up to Dromoland, then two days later from Ashford on a short hop over to Doolin, then the next day thru The Burren, Galway, Connemera to Ashford Castle at Cong. So, he will definitely drive distances on a per-day or multi-day basis.
We recommended him to friends who visited Ireland a year or so later, and they also were super pleased, so much so they offered him an extra condo they own for his overnights when he visited Nashville later that year.
Here is his contact info. I don't know which (if either) cell phone is better. But, you can definitely email him:
