Caregiver Needed

About who needs care: I have been my husband's caretaker for 2 years. He is a cancer patient, confined to a wheelchair and needs someone to oversee safe trips to the bathroom. I can manage the rest of his care. I just need some independent time to myself, out of the house, a few hours a week. About the care needs: Someone who is friendly and OK just chatting or keeping themselves busy independently. Husband can transfer himself from the wheelchair to the toilet, but I need someone to oversee the process for safety. Services needed include: companionship, and mobility assistance.
