I refer to the Duden dictionaries and also ‘Richtiges Deutsch’ (translated as ‘Correct German’) by Walter Heuer for this work. If you would prefer me to use any different guidelines, for example a company style guide, please let me know.
I can read on average 7000 characters (including spaces) per hour, although this does vary according to the text’s complexity and the number of errors.
If you’d like me to suggest smoother alternatives for any awkward phrases on top of simple error correction (see above),
I am happy to do so. This service is recommended when no one else has read your text yet.
