Companion Care Needed For My Mother .

I'm looking for companion care for my mother in her 90s. We're looking for some help preparing meals and companionship. We're looking for someone to help her get ready for bed. Preferences for a caregiver who is a non-smoker and comfortable with pets. She does not have Alzheimer's but has short term memory problems. So may ask the same question more than once. She is super sweet.
