any progressive bilingual schools

Hi, I am looking to move to the Riveria with my young family. Looking for a progressive primary & secondary school that ideally teaches bilingually. From my research these international schools charge 15k/year - which is out of my budget.   In London we attend a Waldorf school ,but the choice of schools in the Riveria seems limited.    Any advise would be very welcomed.  Maybe a, sous contrat, or government school , in nice grounds, caring teaching, accademic - just seems difficult to find.Anthony
