Companion Care Needed

About who needs care: My dad is 78 and had his knee replaced, he's not doing as well as we had anticipated and needs a little help with transportation to hospital visits to Houston VA, making sure he is eating and drinking and just overall wellness checks on a bi-weekly(?) basis. About the care needs: He's cranky and stubborn as hell, and a messy person, especially when he is unable to handle the day to day. We need a caregiver that can buckle through his stubbornness and is confident enough to help someone who may resist a little help. He's recovering from a knee replacement. Services needed include: transportation, feeding, and bathing / dressing.
