Seeking Part-time Senior Care Provider

About who needs care: Mom has dementia, and uses a walker. I need someone that is dependable to help keep an eye on my Mom, to make sure that she is safe, has not fallen, may need to give her a snack or lunch. We also have an exercise bike setup in our living room, and would entail making sure she get on and off safely! About the care needs: They should be helpful, friendly and not on their phone. Services needed include: meal preparation, errands / shopping, and light housekeeping.
