Private classes/babysitter in English

Hello! We're looking for a native speaker to help our daughters, 7 and 11 years old, with their English. It would be two days a week, approximately 2 hours in the afternoon, and we would need her/him to pick them up from school, help them with their homework, speak and play with them, read books, etc, all in English. We live in Las Tablas, close to different means of transportation (subway, bus and metro ligero) 
Feel free to contact us if you are interested.
