Translate a prospectus from Chinese into English

Our clients are investors in the Automotive industry. Recently a company of interest listed on a Chinese stock exchange and lodged a detailed prospectus. The document is rather large and runs to 585 pages. We are interested in having this document translated to English at a high accuracy (we've tried Google translate and the standard is not high enough). We are only interested in translators with a strong grasp of English language. A basic comprehension/familiarity with financial statements would also be an advantage.
