South Korean family looking for helper

We are a Korean family living in Hong Kong, with both parents working. We have been living here for many years. Our child is 9 years old. We are looking for a helper who has experience caring for children of all ages, from infants to high school students. We value responsibility, good organization skills, and the ability to handle children well. In addition, we would like the helper to be able to assist with cleaning, household chores, including car cleaning, and cooking. Thanks
