Lovely, english native speaking Nanny for 2 toddlers

We are looking for a lovely Nanny for our two Kids, boy aged 3 and girl aged 6. We need you 3 times a week (10 hours/week) to pick one kid up and spend time with him/her. The main goal is that our kids improve their english, so a lot of playing, reading, talking is absolutely required.
If you are warm-hearted, caring and responsible we would love to read from you.
