I will return your text free from grammatical and spelling errors. I will suggest changes as needed.

About:

I will proofread and correct any technical text in English. This includes proposals, reports, white papers or other technical documents.
If the text has been automatically translated from a different language, I will require the original text as well.
I proofread and correct the English, I do not write new text. However, I may comment on the text if I see a need for that.
Texts of up to 10,000 words are accepted.
