Care Needed For My Aunt With Dementia (overnight Stays)

I'm looking for live-in home care for my loved one in their 80s. Medication management is required. We're looking for some help preparing meals. Duties include providing companionship and social interaction. Preferences for a caregiver who is a non-smoker, comfortable with pets and CPR / first-aid trained. I need someone to stay 24 hours a day when we go on vacations and also for when I have doctors appointments or other things I can't take her with me to.
