Western Family of 2 Looking for Helper/Nanny - In HK now

I am only considering helper/nanny that is currently living in Hong Kong and not those that have already returned to the Philippines. 

I am a single British father of a 7 year old son and require a helper/nanny to support us in our daily life. Must be great with kids and be able to perform household tasks like cleaning, laundry, ironing and be good at cooking. We also have a small dog and a cat. Must be pleasant, warm and friendly. Assisting in child's homework, tutoring and his well being is important. Obviously, good English language is a must. I am very easy-going and flexible.  My son is the priority in choosing a helper who can take good care of him and act as a nanny, with homework etc.
