Maria, propose une garde d’enfant à Dübendorf

We are Russian-speaking family, with two girls, age 7 and 3.
Initially we would like to have a nanny who could come for one-offs, for the evenings, and then potentially someone who would handle logistics for the girls. (take them to activities, to/from kindergarten, spend evenings with them etc.) For the logistics, it is possible to do without a car, but having a car saves ~20-30 minutes one way.
Girls speak Russian and German (older one speaks French also). They are pretty easy-going.
