English Babysitter in Pozuelo de Alarcón

Hi, we are looking for a native English or American babysitter in Pozuelo de Alarcón to play with our 4 year old kid. 
It would be 2 days a week from 5pm to 8 pm (6 hours per week) starting on September. 
We expect the babysitter to speak English at all time. Our kid already understands English. No other duties required other than play with him and speak in English at all times.
We are paying 10 euros/hour.
Please contact me at my email if interested.
Many thanks.
