Companion Care Needed - Full-time / Part-time

My 70-year-old father is having knee surgery and we are looking for caregiving support. He is otherwise independent so care would generally involve helping him stay on top of a medication schedule, light housekeeping (tidying kitchen, cleaning cat box, some laundry), mobility assistance (he will have a walker), meal preparation, assisting with physical therapy, and just being present in case a fall or something were to happen.
