We have a 90 page document (actual text more like 25 pages single-spaced) which was translated into English. It should be fairly easy, we just need the grammar corrected so it sounds clean and natural, the translator is not quite a native level speaker.
If you don't understand any areas you can highlight that text and the translator can review and correct. You'll be asked to review any updates, so one pass through it for corrections, then review highlights (if any) that you don't understand after they're clarified.
Please provide some example of your previous work.
This is the file to be corrected:
