Looking to share a Mandarin speaking helper

We are a British/German family and recently moved to Hong Kong. We used to live in Beijing for 3.5 years before that and our son was born there. We are looking to share a Mandarin speaking helper, English is not a must. We have a 4 year old son and would like a motivated, active and loving helper to look after him half day from January.

 

Does anybody have a similar request or willing to share their helper? Please contact me with any suggestions!
