I get short translations I need done pretty quickly from time to time. Japanese to English , copying Japanese from PDF to Word, English to Japanese. As well I get longer jobs too. The freelancer should be online and able to do short translations on a moments notice with 2 hour turnaround. Often these are single sentences, so not long. Longer translations can be hundreds of words.
6 yen/english word (from English to Japanese), or 6 yen/2 japanese moji (from Japanese to English) and 2 yen / moji when simply copying Japanese text read from a PDF to a word file. For small ongoing translations, I can pay $30 each time until the word limit is used up and then add more money.
