I've been intensively studying Chinese language and Chinese philosophy in China for five years. I myself am Lithuanian, but I'm fluent in English, besides my American friend, who is fluent in Chinese as well, will colloborate with me for proofreading. Other than that, my wife is Chinese who is always in my team. Translation is not a mechanical job, so we need more time to translate such amount of text. Would be nice to know in advance the type of contents you provide. Whether it is literature, technical stuff or something else.
