Western family seeking helper in HK

We are a couple (USA husband, Taiwan wife) who have lived in HK many years. Our 1400 sq foot village house is in the New Territories, but close to bus lines to Taipo. Our children are grown and have left HK, but we need help keeping up with the housework, a small garden and general cleaning, laundry, etc. We have had several helpers in HK and are experienced and reasonable employers. We look for an honest and diligent helper, and can offer one day a week off, standard salary, and a small private room for sleeping arrangements.
