Companion Care Needed - Full-time / Part-time

I am looking for care for my grandfather. He is in his 80s with Parkinson's and dementia whom recently broke his hip. He's cognitive state comes in and out. There is other people in the house but are unable to help with mobility. He is currently in rehab but will need help when he comes home. We will need care daily in two sessions, a morning session and late afternoon session. Times to be discussed. He will need help with activities of daily living, getting around the house, exercise, eating, taking medications and bathing.
