Kind & patient helper needed, special needs child

We are a family of 3. We are Chinese American professionals living in Hong Kong and we have a demanding schedule for home, school, and work. Mrs will be working and studying from home. We speak mostly English. Our son is 11 years old and has special needs, therefore we need a helper which will be kind, warm, and very patient with him. He's a sweet little boy. Also, cleaning and good hygiene is VERY important to us. Your duties will include caring for him, attending school with him part of the time, cooking, cleaning, and other domestic chores for the family. We would need someone who has a good attitude, is willing to learn, flexible, detailed-oriented, thorough, and extremely hardworking. You will naturally be teaching and helping our son a lot so we need a good natured person, kind-hearted, and super patient. If you have experience or a degree with special needs, teaching or nursing background, please let us know.
