English Native for kids

We´re looking for an English native speaker to take our kids from school at 12.45 and bring them back at 14.45. During this time, they would play and talk in English and he/she would give them the meal (already prepared). It´s from monday to friday and the kids have 9, 9 and 5 years old.
We´re living in the north of Madrid (Las Tablas).
