Western family looking for a long term helper

Good day,

We are a family of 3. Our boy has six years old. We are looking for a caring helper to look after our boy and housekeeping. My husband is from the Caribbean, and I'm from South America. Our primary language at home is English. We don't have parties at home, and we don't drink/smoke. No pets. We are mainly looking for someone committed to the work, hardworking, honest, responsible, and proactive/supportive of home learning. We like to eat western food, and I like to have everything organized and tidy. 

We are looking for someone who can stay with us for a long-term contract.
