Western family , experience with autistic kid

Hello, my family and I are looking for a helper to start with us in June  . We are relocating from Singapore to Hong Kong ( discovery bay) 

Our son Teddy is 3 yo and has autism so preferably all candidates need to have experience in this area. We also have a daughter Penny who is 5 yo so would like someone who has at least 2 years experience with young kids. 

Please enquire only if you suite these requirements, thank you
