Senior Helper - 90 Year Old Couple Needs Part-Time Help For 5-6 Days

I am looking for help for my father (who has Alzheimer's) and my step-mother in their home next week while their helper is away. For the most part they stay in their bedroom upstairs. They have a stair lift you are welcome to use. Duties throughout the week would include things such as changing sheets on a king-size bed, emptying trash, filling drink mugs, preparing and bringing up simple meals and snacks, feeding their small dog, laundry, dishes, straightening, light housework, bringing in mail and deliveries, putting groceries away, etc. while you are there. Hours may be adjusted. The regular helper may be back Friday.
