English for kids

I'm looking for a native teacher for our kids (10 years old girl and 8 years old boy) using only Story Telling, Games, Role play and Conversation (Neither grammar nor written english)

We're thinking about 4 hours / week, from October 2014 to June 2015.

We live in Leganes 5 minutes away San Nicasio's Metro stop.

Please sent CV. I'd like to know your experience teaching english to kids
