Hello,
This sounds like a job that I would be perfect for.
I am a Czech native who is fluent in English and I have experience teaching Czech and English. I don´t speak Russian, but I am sure we would make the communication work without any problems, as Czech language is quite similar to Russian. Please let me know, how often you would like to have the lessons and we can also discuss the price. I live in Prague and I am very time flexible. My rate is 10 USD/hour, but it could be negotiable.
Kind regards,
Dominika
