Russian, French, Or Spanish Speaking Nanny/tutor To Help Teach 3 Boys To Speak (English Too)

Seeking foreign language speaking nanny and/or tutor (not clear on the most appropriate title) to take care of / tutor / work with our children one day per week. Would start with two of our boys and eventually include the third as he got a little older. The ideal candidate can speak fluent Russian, although will also entertain candidates that can speak fluent French or Spanish. No housekeeping, the entire focus is on keeping children alive and adding some diversification to their routine / education. Talking and language is the primary focus along with the normal developmental games that accompany that. A team of 2 is acceptable if that is your preference and you can help facilitate. We have two small dogs, we can crate them if they're an issue. They're harmless and fluffy, though.
