Looking for private driver with large van reccommendations

Hello, my family of 4 will be visiting my FIL and other elderly relatives in late December. Is there a recommended private driver company that visitors use? My husband is Korean-American but he can’t speak Korean well.

Our plan is to pick up FIL and husbands cousin in the morning, who live Seoul and then drive down to Gwangju / Jindo, have lunch and/or dinner there then drive back in evening back to Seoul.

FIL wanted to drive himself and rent a van but we’d rather him not drive because he’s old and has a bad back. We asked him to look for a private driver but he’s trying to override our wishes. 😬 My husband prefers not to drive or go through trouble of renting a car.

Please recommend companies who are experienced with driving around tourists with good communication and willing to stand by while we do our family activities. Thanks in advance !
