Teaching English in Russia and Ukraine

I am seriously thinking about teaching English in Russia or Ukraine. I am going to get my ESL certificate and then find a job teaching English there. I earned my bachelor's degree in a college/university in 2008. I have some questions I hope one or some of you can answer for me. Is there a demand for native English teachers? Since I do not know any Russian except I can read only a very few words, how difficult will it be for me to do every day things like grocery shopping, using public transportation, etc. I want to learn your culture and language. I know it will not be easy for me to learn the Russian language. But I want to learn just enough to get me bye on day to day activities. This would be an adventure of a lifetime, if I can make this possible. It will be great if I can find love in your country. If not, I will value greatly of all the wonderful people I have yet to meet. Your thoughts, please.
