Please be kind enough to translate the attached document of 3,700 words.
I would ask that while this is a trial for a major project, please do not spend longer on it than you would any other work - that is important as we both have to be happy we are being well paid for what we do. That being said, it is important that the translation is accurate in fact, as it is my job to fine tune the English. In other words. please make sure that it makes sense.
If you have a problem with any area of translation, or you are unsure, rather than guessing, please just add a side note to the translated copy indicating your concern and highlight the text. I have attached a document with an example of how it should look. Please also highlight the text in the original for easy reference, but there is not need to repeat the comment in Russian.
I would be grateful if you could return this to me by next Thursday, at the end of the day, if that is possible.
