HK-Malaysian family looking for a helper - Wanchai

We are a family of three - my wife, my 2-year-old son and myself - living in a 800 sq. ft apartment in Wanchai. We are looking for a kind, patient and hardworking helper with positive energy to join us in January (ideally on or around 8 January). 

The main tasks are to look after our son, do housework, do groceries in the wet market and cooking. Our son is already going to playgroups and is expected to start nursery soon. We would like the new helper to bring him to/from school, accompany him to playrooms and playgrounds in our clubhouse, do his baths, and prepare his meals.

The helper will have her own room in our apartment (approx. 80 sq ft), and the expected working hours will be 6:30am - 9:30pm (covering our son's awake time).
