Looking for helper in HK

We are a family of four people. We are both working couples with two kids. They are currently 7 yr old boy and 10 yr old boy. They are now attending full day primary school. The main duties includes taking care of my sons ( go to school and tutorial class), simple cooking and normal cleaning housework. We lives in Kowloon with around 880 sq feet. There is a room and washing machine for helper. Sunday holiday. Please let me know if you are interested.
