Western family looking for domestic helper

We are a Canadian family moving to Hong Kong in mid-August. My husband and I are school teachers. We have three elementary school-aged children. Before our children were born, my husband and I lived in Hong Kong for seven years. We are excited to return! We are primarily looking for someone to provide childcare as needed, and to help with general housekeeping. Our children are ages 11, 9, and 5 years old. We are looking for someone who enjoys children and would like to share our HK adventure together with us.
