Housekeeper

I am trying to find a housekeeper for my grandma's house. Recently she needs to take care of my cousins and is stressed out over maintaining her home. She keeps the house tidy overall but needs help with the weekly maintenance cleaning the bathroom, vacuum, changing sheets, etc. Nothing needs to be deep cleaned just maintained without her needing to worry. I am worried about her health and I dont think she should be cleaning on her own as much as she does.
