Caregiver/Sitter needed for elderly father

Looking for a caregiver who would act more as a Sitter for times we need to be out and leave my Father, we don't wish him to be alone. Required to be responsible for his wellbeing, fix him food occasionally. He is nearly 85 years old and sleeps most of the time with frequent bathroom trips and regular meals required. He is suffering from onset alzheimers/dimensia but is not violent and communicates well. Additional contact number is 616-534-.... This would be a very occasional need, mainly hourly/daily only as needed.
