Hi Hans, How are you? I can get this done in 15 hours. I am a native English speaker and professional writer, and editor from the United States. I will edit, spell, do grammar and punctuation checks, style, syntax, basic formatting, and word choice (readability, wordiness, clichés, and jargon) in a quick manner. I'll make sure that your writing is error-free and ready for publication.
Please send me a message, I will return your proofread content with the track changes feature activated.
Regards,
Johnson
