Looking for a diligent and thrifty foreign maid family

There are three people in our family, a husband and wife and a three-and-a-half-year-old child. The worker sister needs to be responsible for the whole family's three meals a day, taking the children to school, and doing daily housework. The children sleep with their parents at night. We are still looking at the house. We plan to rent a small two-bedroom apartment in Mong Kok or Sha Tin in Hong Kong. We will try to provide a separate room to the worker sister according to the situation. I hope that the worker sister belongs to the diligent and thrifty type and reasonably control the cost of living. As an ordinary working family, we hope to work in our family for a long time.
