Companion Care Needed - Full-time / Part-time

We need someone to come in and be with my mother in Goleta for about 3 hours a day, a couple days a week. We would prefer someone who can handle light housekeeping and/or helping her water the garden, go on short walks, or take on short outings to get lunch or coffee. Some light meal preparation. Potentially assist with showering from time to time, but not required. Preferences for a caregiver who is a non-smoker.
