Looking for a long-term helper to join our family of 3

Hello, we are a Hongkongese couple, looking for a long-term helper to take care of our 3-year-old son while we are at work and do basic household chores. We are looking for someone who:

-    speaks good English as it will be our boy's main language (knowledge of Cantonese/Mandarin will be an advantage but not a must)

-    loves children and is happy and patient to take care of/teach/play with them

-   is going to finish her contract/has her contract terminated for good reasons (such as relocation of employer but proof must be provided)

-   is available for a face-to-face interview on Sat or Sun

Priority and higher salary will be given to those who has a reference letter or can provide the telephone number of their current employer for reference check purpose.
