Family looking for helper

We are a family of 3- Sir, Ma'am and 13 yr old boy. We are looking for a helper who enjoys cooking and is willing to learn more. The job scope is general housekeeping and cooking. Since we are a small family and my son is already 13yrs, I expect the job to be done well with honesty and care. I would like my helper to be well organised and have a high standard for hygiene personally for herself and for the house. Basic good manners and respect for all in the family is important.
