British family seeking helper with baby/childcare experience

We are a British family based in Sai Kung with a six month old daughter and a two year old son. We are looking for a reliable, trustworthy, positive person who loves taking care of pre-school children. Main duties childcare, cleaning and laundry. Some cooking and a few outdoor chores too (eg car washing and mowing small garden), occasional evenings babysitting. Someone who is great with the kids and will keep them safe and happy is our top priority. Looking for finished contract/terminated due to relocation with excellent references. We have a full village house and can offer your own room (ground floor with window and A/C) and bathroom. Ideally looking for someone who plans to stay in Hong Kong for at least the next 5 years. Start date negotiable for right person.
