English native speaker for three kids.Pozuelo/Aravaca

I look for an English native speaker to teach my kids of 2, 6 and 8 years old.I live in Pozuelo close to Aravaca station.
From Moncloa you can take the bus 657, or by Cernanias from Principe Pio to Aravaca and then 10min walking.

12€/h and 5h per week, that means 240€/month.
Sunday: from 11 to 13h.
Monday & Wednesday: from 18.30 to 20h.
Thank you very much.
