Aide And Companion For Senior Citizen

We're looking for an aide and companion for my mother-in-law who is currently living in an assisted living facility. She had knee replacement surgery in July and is currently receiving physical therapy to help regain her mobility. We'd like someone who can walk with my mother-in-law. Other tasks include helping getting in and out of the bathroom. We'd also like the aide to help my mother-in-law when she visits our home or goes to a restaurant outside of the assisted living facility.
