Companion Care Needed - Full-time / Part-time

I'm looking for someone to stay with my mother-in-law on an as needed basis. It would be for a few hours every once in a while, with no set schedule. She has COPD and an element of fall risks and is not safe to be left alone. There may be times when serving her a meal may be necessary. She does not need to go to any appointments, and this will be strictly sitting with her in our home. Thank you for looking. 3 dogs in the house. We also have barn cats.
