Companion Care Needed - Full-time / Part-time

I'm looking for someone to spend a couple of hours a day with husband, Monday through Friday. Ideally, that would include taking him out for lunch at a fast-food restaurant of his choice, encouraging him to get some exercise a few days each week, and on the remaining days taking him to his office in Clayton, where he can spend an hour or so if he wishes. My husband has dementia, is very docile, and does not talk much. At this stage he takes care of his own hygiene, however wears adult diapers.
