Companion Care Needed For My Mother In Beverly Hills

About who needs care: My mother is quite active but both she and her husband (both age 94) need some daily attention (go on errands -- my mother loves to shop) prepare some meals they can heat up, do some minor chores (they have a housekeeper who cleans every other week). B is pretty sedentary. They have a small dog that needs to go out twice a day. About the care needs: Kindness and tolerance of their deafness and forgetfulness is most important. My mother's up and down glucose level can be a challenge (crabby on one end and forgetful on the other). They have NO computer access (they have internet access but no device). My step-sister is in Ft Lauderdale and comes up once a month. She handles their finances etc as she has power of attorney. I live nearby but work full time. Services needed include: transportation, meal preparation, errands / shopping, light housekeeping, and companionship.
