Your approach to business is truly professionall. Or you are paranoid about your interpreters :) Either way, Ukrainian is a beautiful language, so I wish you the strengh and motivation to handle your intent. There are not many people here learning it, so you can expect a lot of attention from Ukrainian-speaking community. That should help you too. Though, I'd suggest you to also look into Russian. Vast majority of Ukraine is bilingual and except for the West, I'd say that Russian is more popular (from my experience of being in all other parts of the country). It is much more world-spread as well. Good luck! PS. I'm just curious, why did you draw dots ".." after and's? Is it some Korean punctuation habit? Like that closing bracket ")))" overuse that many Russians tend to :)

Are you sure that you need it? I'm sure any person you'll deal with will able to speak you in English. Anyway if it is interesting for you, you'are welcome.
