British Chinese family looking for a domestic helper

We are a simple and open family looking for a domestic helper to independently care for a 9 months baby, clean the house and cook daily, and also to help prepare a 4 years old to whole day school but no need to take him to school or take care of him much. We live in Mei Foo and is keen to find someone who is honest and loyal and willing to finish contract to provide stability for the baby.
