Renting a car in Oberic?

Greetings! Traveling to Oberic before I meet my family in Split mid September. I REALLY don't want to do the drive from Dubrovnik to Oberic alone as I don't drive that much and I am a bit freaked out by windy roads and cliffs, ect. I AM however thinking of renting a car for a few days while I am in Oberic so I can explore and also take the car ferry to Korcula. Any advice on car rental in Oberic? Seems to be only local places. Thanks!
