Babysitter Needed - Now Hiring

We are looking for a full-time nanny for our twins (a boy and a girl). Our timeframe is mid-November in San Francisco, but we might need part-time nanny starting in early September (3 days a week in Santa Rosa). Early child development experience and knowledge of Russian is required, as my parents do not speak English and I want to ensure kids are raised bilingual, able to communicate with their grandparents. This employment opportunity would be for 1 to 3 years, until kids enter pre-school.
