Family of 4, looking for responsible helper

We are a family of 4 ( 2 kids 16 and 13 yrs). Our older kid study in boarding school outside HK, so most days it's 3 of us at home. We are both working and looking for someone trustworthy who can manage house independently. Since our kids are old and independant, we are mainly looking for someone who can manage daily household chores and cook(asian, non-asian food). We live in a house at a convenient location in Clearwaterbay. 4 min walk to bus stop, walking distance to groceries.

We believe in happy relationship with our helper, providing respectful work environment and yearly ticket back to their home country.
