Native English Private Tutor

We are looking for a native English speaker, preferably a female from the UK, to spend some time with my two daughters. They are 5 and 6 and speak and understand good English. However, since we have moved here last year, they are slowly losing theyr hold of the language. Candidates should be able to spend 1 to 2 hours, 3 times a week, teaching them the language through fun activities.
