I am searching a native english teacher for children

Hello
I have 2 children of 4 and 5 years old and I would like them to learn english in a natural, fun and interactive way. 
I would like count on a native english teacher that can come at our home to play with them 1 day per week during 1 hour or 1,5 hour. We leave in Madrid, in Sanchinarro neighbourhood, 
Would you be interested? if so please contact me on by email or whatsapp
Thank you 
Best Regards
