Hands-on Care Needed For My Mother In Bedford

I'm looking for hands-on care for my mother in her 90s. We would prefer someone who can handle light housekeeping. We're looking for some help preparing meals. We'll need you to handle groceries or errands when appropriate. She can bathe herself but we worry about her getting in and out of the tub. We want to start with 2 days a week but might move to 3. Preferences for a caregiver who is a non-smoker and CPR / first-aid trained.
