British Korean family looking for a full time helper

We're a British/Korean family with a 5y old son living in SaiWanHo. We're looking for a live-in fulltime helper who loves kids and cooking, and is willing to follow instructions. Mother works part-time and she does most child care during midweek. Both parents are hands-on on childcare.
Main duties for our new helper are cooking, grocery shopping, housekeeping(cleaning, laundry, etc) and short hours of child care(when I need to work). Child care would be only around 5~7 hours a week. Even though child care is supplementary work, it is the most important duty. we look for someone who truely cares about kids and enjoys playing with kids. Our flat has 3 bedrooms. One of the seaview room is for you. It has bed, storage and basic furniture. We pay the food allowance.
