A great lady needs a little help and companionship

My mother is 89 years old she suffers from dementia/alzhiemers. She is pleasant and can still hold a pretty good conversation. She needs promoting to get through the day as she is very forgetful and easily confused. A little help in toileting is needed. Meds will need to be given a.m. and p.m. She sleeps pretty well at night but can be up and restless at times.. a cup of tea and cookies seem to settle her.. She lives in a Senior apartment complex with a central dining room, so no cooking is needed. She currently has two amazing caregivers with her, one day and one night. They need a day off! I need someone for the weekends, Saturday morning until Monday morning. I do not have an extra bedroom, only a daybed in the living room. Budget is limited.
