English native speaker for kids

We are looking for an English native speaker student to come to our house to play and speak with our kids (4 and 2 years). It's not a babysitting job, as their mother or I would be always present. We want 1 hour and a half or 2 per week preferably on Fridays afternoons, although we can study other possibilities. We live in Torrejón de Ardoz which is very close to Alcalá by bus or train. Salary per hour to negiotate
