Looking for a suitable helper for our small family

We are a Chinese Singaporean family of 3 (2 adults and 1 child who is 5 years old). We live in a 3 bedroom condominium and our helper has her own room. We are looking for someone who can care for my little boy (picking and sending to school, taking care of him), cook well for us, general housekeeping duties (Laundry, cleaning and keeping house tidy) as well as makreting for food. We have no pets
