Companion Care Needed - Full-time / Part-time

My grandpa has dialysis 3 times a week (MWF) starting around 6 a.m. and ending around 12 pm, I am looking for someone to drive him to and from the appointments. The clinic is only a few minutes from their house. If I can find one person to take him there and one for the way back that would work fine too. It's not likely that you would need to be inside the home much at all but there is a cat living there who would be in a separate room but just a consideration if you have any allergies.
