Companion Care Needed

About who needs care: My stepmother, Diane, has suffered severe rheumatoid arthritis for many years. She has had multiple joint replacements and her ability to care for herself is diminishing. She does not really have hobbies because her hands are not very functional. She is around 125 pounds and is just barely able to transition from bed to wheelchair, etc. About the care needs: Diane needs help with personal care, showering, etc. My parents have a dog who is a bit yappy and annoying. Services needed include: meal preparation, errands / shopping, light housekeeping, feeding, bathing / dressing, and mobility assistance.
