I have been a professional translator for more than I can remember, and my clients include Sydney Opera House, Opera Australia, Tongzhou Yoga, and quite a few other small business. Meanwhile, I am a writer and editor. In this industry, accuracy, meeting deadline and creative languages are basic elements.
1300 words within 5 hours is not a problem, but I would like to know the content, and what it is about before I can 100% guarantee, and that's what a responsible translator should do.
