Companion Care Needed

About who needs care: Elderly, uses a Walker. Need most help with Appointments, getting her to eat right and regular. And a friend to chat with. She likes to paint but is going blind so maybe someone to motivate her to do it while she can still. I am her son and live with her but I work from 11 a.m. to 730 p.m. Monday through Friday and have already used all my Sick and Vacation days to take care of her. It won't be everyday but would like a regular schedule worked up Services needed include: transportation, meal preparation, errands / shopping, light housekeeping, and companionship.
