I am interested too. We were looking for one a few months ago but had to give up because we didn't find a bigger place to live to accomadate an au pair. So now I am going cak to school in the fall and have to find childcare for dd2.
I was an au pair and I used an online search site and that is how my family found me. I was using 3 similar sites to serach for an au pair. I think it works out well.
Mamma to dd1 3/8/07, one 9.5.08, and dd2 9/9/09
