Companion Care Needed

I'm looking for part-time companion care for my mother in her 80s. What we need: - Saturdays and Sundays (morning to early evening) / Wednesdays if possible - Drive her to and from appointments - Errands as needed (grocery shopping, prescription pick up, etc) - Prepare her meals - Feed and walk her small dog - light housekeeping as needed We need someone with their own vehicle and our preference is for a caregiver who is a non-smoker. Thank you so much.
