Companion Care Needed

I need a companion care provider for my adult sister in her 20s. She has high functioning autism but needs regular assistance with executive functioning tasks, including taking care of herself and her environment. Some light tidying up is involved. We're looking for some help preparing meals. We're looking for someone to provide companionship. We'll need you to handle groceries or errands when appropriate. Preferences for a caregiver who is a non-smoker and comfortable with pets. She has a cat.
