Companion Care Needed For My Mother

I need a companion care provider experience for my mother in her 90s. We're looking for someone to provide companionship. Duties include transportation (doctor's appointments, errands, etc.). Preferences for a caregiver who is a non-smoker. It is her great grand daughter wedding and need someone to help her for the evening. Take her to the venue and stay with her though the wedding and reception. Take her home after.
