Take care of 75-year-old man

There are only two elderly people in the family. Now there is a domestic helper who is very easy to get along with and mainly cooks and does housework. Now we need to hire another helper to mainly take care of a 75-year-old man who is currently unable to walk on his own, but has a clear mind. Both elderly people are very kind. The house is 1,000 square feet and has a spacious living space.
