Cecile, cherche une garde temps partiel - 75015 Paris 15ème arrondissement

English native sitter,
I am looking for an english native speaking student to help take care of my two sons aged 7 and 11.
They need to be picked up every Friday afternoons at their dad's who lives in Houdan, an hour away on the N train. You would have to be available on Fridays to take the 4.58pm train alone in Montparnasse, pick them up at the station on Houdan and ride the train back with them to Paris, then back home in bus to my place in the 15th.
They need to practice their English and are very active and fun.
Thanks!
