Companion Care Needed For My Grandfather In Naples

I'm looking for companion care for my grandfather. He just turned 89 and while still pretty active for his age is starting to need help with housework, grocery shopping, errands, meal prep, personal hygiene, transportation, keeping active, and taking care of his Boston Terrier. Most importantly looking for someone to keep him company and help keep his spirits high and his mind sharp. He's suffering also from Parkinson's Disease symptoms and may need increasing help with mobility. Right now we are looking for someone to come in on weekends to assist him but this may grow into a full time or live in position in the future depending on his needs. Preferences for a caregiver who is a non-smoker, has their own transportation, is comfortable with pets and CPR / first-aid trained.
