Companion Care Needed - Full-time / Part-time

About who needs care: Shes 86 years old. She needs help getting up and walking and to the bathroom to take shower. About the care needs: I think at the start of having dementia. She just needs someone to be there with her and help her get around the house and maybe cook a light meal for her at lunch. All she wants to do is stay in the bed and the doctors need her to walk around and get fluid away from her heart and her legs. Services needed include: meal preparation, errands / shopping, light housekeeping, feeding, and bathing / dressing.
