Looking a helper for grandpa

We are a family of 4 adults and 1 child.I'm looking for a helper to take care of grandpa(a disabled elderly men).Your daily work including take care of grandpa (change diapers/pads, wash face, brush teeth, wipe body, measure the elderly’s blood sugar, blood pressure,simple joint exercises, wheelchair strolls for sunlight) and do the house work.

PS: In special case, if other family members are unavailable to pick up or drop off the child, assistance may be required, but as take care of the child is not included in your job require, we will give you 20HK$/H as a extra allowance.

Our house is small and have no anther room for helper, you need to share room with grandma, she is a very nice old lady.But if an independent private room is your must need,grandma is willing to sleep in the living room and let you have the whole bed room.
