Companion Care Needed - Full-time / Part-time

I'm looking for hands-on care for my grandfather in his 90s. Important - experience with managing and administering medication is required. Some light tidying up is involved. Seeking someone to handle meal preparation. We're looking for someone to provide companionship. We might ask you to run errands now and then. Duties include transportation (doctor's appointments, errands, etc.). Preferences for a caregiver who is a non-smoker.
