Caregiver Needed - Full-time / Part-time

I'm looking for an elder sitter for my loved one who is 86. What is needed is to be in the house in case emergencies arise. Provide drinks, snacks and warm up meals and deliver them to her in her room. Remind her to sit up when she eats and get out of bed every two hours. Preferences for a caregiver who is a non-smoker and comfortable with pets as we have two dogs and a cat.
