Looking for Domestic helper

We are a simple family with 2 adults and 1  seven years old boy. We are also expecting a new baby in Sep 2019.

We mainly need a helper who firstly needs to be honest and trustworthy. Secondly, we expect the helper can cook well in Chinese food - as mainly serve the kid, food must be fresh and nutritious.

The third,  she should be able to to take care of a new born baby while the parents and nanny is not around. And do the basic housework.

Helper will have separate room in my place. We can offer all The Sundays as off day.

Christian helpers will be preferable to apply. We live in Ma Wan.
