Retired couple looking for a helper with outdoor garden work

We are a retired couple British/Chinese American looking for a helper who is very clean, tidy, organized, and loves plants. We live in a quiet Shatin village with a big garden. We provide a separate helper accommodation. Helper’s main job duty: house cleaning, laundry and ironing, gardening, watering plants, outdoor cleaning, and car washing. The helper needs to be mature and responsible, who can follow instructions very well, and can work without supervision when employers travel.
