UK/ HK fam (1 baby+1 kid) looking for good cook

We are a HK/ UK family with a 3.5 year old son and a new baby due in October. We live in Mid-Levels near Wan Chai and are looking for a kind and responsible helper to join our family from Aug. The main responsibilities will be to clean, meal plan and cook healthy meals (Chinese and Western vegetarian --husband and kids do not eat meat), and also to support caring for the new baby in the fall. Will work independently, with own bedroom and bathroom. 

If interested, please tell me more about yourself, your past experience and daily routines.
