A family looking for a helper

Two adults and one child, the kid that she is 2.5 years old. The employer's house is 550 square feet, with two rooms, one for the helper and the child. However, at the beginning, the child should not be familiar with the helper, so they will sleep with the employer, so the helper will have their own room. Helpers can rest on Sundays. Monthly salary of HKD 5500. I need to find a completion assistant who has a good English proficiency and good at cooking.
