I possess an excellent vocabulary and knowledge of English language spelling, grammar, usage, idiom, and sentence structure.  The last time I did a major project, I was running through 27 pages per hour, with no more than up to three errors in the entire document when I was finished (most of them were stylistic).  My services are free of charge for people translating games into English from Japanese, but I cannot help with the actual translating.  Either message me or e-mail me at alaras12@aim.com if you are interested in my services.
