Companion Care Needed For My Father In Colorado Springs

We need two overnight care providers to help my father, about to turn 80, get to and from the toilet during sleep periods. Caregiver will need to be able to prevent falls of 160lb man and help out of bed and up from seated position on toilet; there are no other duties required. Goal is give one provider 32 hours/week and the other 24 hours/week, consecutive days, with option to call other provider if unable to serve on a scheduled night. Father will be asleep 90%+ of time, but caregiver will enable Mother to sleep a full night before taking care of him during the day. Father has Parkinson's disease.
