Looking for a reliable, trustworthy helper

We are a Korean family of 2 adults and 2 kids and are looking for a sincere auntie for our kids. The main duties are generic households as well as cooking including the lunch box prep for the kids. Our current helper who has been with us almost 8 years needs to go back to her country for a family reason. We prefer someone already in HK who has finished 4yeats contract with 1 employer or termination because of employer's relocation.
