Au pair

Hello

I am looking an au pair for my 8 year old educated partly Dutch in an American school.
The "deal" would be to keep my daughter 4/5 hours per day (in the evening). Us prevoyerons two days of rest per week including 1 the wk.
The AU would be housed and fed.
We live in an apartment of 250 m2 with swimming pool and private facilities for each rooms.
My daughter is adorable, very social and autonomous except partially for homework.
Ideally the profile would be a student speaking English and having the B permit.
I am however open to any interesting proposal given that the AU has his day at disposal, so this "job" is compatible with any other occupation.
