Interesting to read your post - I don't come across many translators! May I ask who you did it for and what you charged? And why you stopped - coding just more lucrative or interesting?
I normally charge 7-7.5p/word, but am accepting 6p when they give me a reasonably decent machine translation draft. It suits my lifestyle because I need to earn well for a few years before I retire, for family reasons, and the ability to pick and choose jobs fits well with having a day job and intermittent private stuff. A zero-hours contract, of course, ironically, but that's OK when I can turn work down.
