English kindergarten teacher is needed

Hello, We are a family living in Mundet area in Barcelona looking for a responsible native English speaker kindergarten teacher/tutor for our 5 year old and 3 year old. Looking to do it 4 times a week and possibly from 3pm-5pm or 2.30 pm-5pm (to be defined) from Monday to Thursday.  Must have previous experience and recommendations would be valuable.  Any recommendations will be much appreciated. Thank you.
