Companion Care Needed

I need a locally-based companion care provider for my mother in her 70s. We're looking for someone to provide companionship and check in on her - perhaps a couple of hours a week, maybe more depending on her needs. She always needs help figuring out her phone! The schedule is flexible - we are really looking for someone friendly and warm to look out for her. It's possible she might ask you to handle groceries or errands when appropriate (although she loves grocery shopping herself!). Preferences for a caregiver who is a non-smoker.
