Companion Care Needed - Full-time / Part-time

We are looking for a part time caregiver for my mom. The caregiver would bring her to dialysis and sit with her there to give companionship and help drain her Ostomy bag as needed. Its pretty simple and not hard work as there are several dialysis nurses at the facility. I just go with her to these appointments now and we would feel most comfortable with someone there to help as needed.
