I need trivia for a Japanese game

I need someone to help write some quiz questions for a game to be released in Japan. It needs to be written in English but is about Japanese culture (history, trends etc).

The questions are multiple choice (1 correct answer, 3 incorrect answers) and must have plausible incorrect answers so the candidate must have a good knowledge of Japanese culture (including music, tv shows, movies, celebrities etc) and/or speak Japanese to be able to research it on the web.

Budget is based on 1,000 questions (£0.25 per question) but we may need more content (so the budget will rise accordingly). If you don't have time to do all 1,000 please don't be put off as I can potentially split across multiple writers.

My deadline is end of March.

Thanks
