Companion Care Needed

About who needs care: She is elderly. We are working towards getting her approved for right shoulder replacement surgery. She is a fall risk. She can clean herself, and occasionally fix own meals. About the care needs: I don't want to leave her alone for more than a day without supervision. I am looking for caregiving on an occasional basis which will be based on me being away from home on an overnight(s) basis. While here, attend to her cleaning and making sure she has food ready to eat. Services needed include: meal preparation, errands / shopping, light housekeeping, feeding, and bathing / dressing.
