Hong Kong family with a baby looking for a helper

We are a Hong Kong couple with a 2 month old baby living in Jardine's Lookout. 

We are looking for a helper to start in November and the expected salary is HKD 5000-7000. 

The primary duties will be baby caring, housekeeping and cooking. There will be another helper in the flat so we will need someone who is willing to work with another helper.
