You write that you need translation of the text of the site from English into Russian and Ukrainian. Good. I'm completely Russian and Ukrainian, so it turned out that in the region where I live everybody knows two languages and a part of the population speaks two languages as radically. Translation from English into Russian, from Russian to Ukrainian or vice versa will not solve any problems. I will say more to translation site from Russian to Ukrainian not necessary, because all Ukrainians know and understand (they can read) Russian has developed historically, so it's enough to translate the site into Russian but adopt.
Second, there is a problem in communicating in English, I study jazik but speak and grammar while neochen, ie what is written on the site in English, I understand and translate into Russian or Ukrainian at will, but correctly grammotically back to sozheleniyu yet nesmogu.
But fortunately, good luck in a good translation.
P.S. Nezibivai translate the site into Ukrainian is good but not necessary, because Ukrainians are very literate people and speak 2 lengvich.
