Looking for a diligent and frugal foreign nanny family

Our family consists of three members, husband and wife, and a three-and-a-half-year-old child. The address is in Mong Kok, Hong Kong, with a house area of about 500 square feet, and there is a large balcony for growing flowers. The helper will need to be responsible for cooking three meals a day for the family, taking the child to school, and managing daily household chores. The child sleeps with the parents at night. We are also looking for a house, planning to rent a small two-bedroom apartment in Mong Kok or Sha Tin. We will try to provide a separate room for the helper sister depending on the situation. I hope the helper sister is hardworking and frugal, reasonably controlling living costs. As an ordinary working family, we hope to work long-term in our home.
