Companion Care Needed

About who needs care: My mother is 89 and walks with a cane. She needs someone to take her to the grocery store and Walgreens once a week and occasionally to a doctor's appointment. She owns a car but is willing to ride in the caregiver's car as well. About the care needs: Someone tidy, 30 to 60 years old. My mother is an artist and likes to paint. She still lives on her own and likes her independence. Depending on the make/model, she may, from time to time, need help getting in and out of the car. But overall, she is still steady on her feet. She is 5'7" and weighs about 145 lbs. Services needed include: transportation.
