Companion Care Needed

I need a hands-on care provider about 2 times a week for my mother who is 85. Times and days are flexible. She is still with it and doesn't complain. She has CHF(pacemaker, stable on medication) and spinal stenosis with severe arthritis. Some light tidying up that includes vacuuming, dusting and tidying bathroom. We're looking for someone to provide companionship. Assist in walking to bathroom when legs are weak. Preferences for a caregiver who is a non-smoker and CPR / first-aid trained.
