Hi, I believe that I could roughly do 2000 words per hour (usually only 1000-1500) as the writer being a professional their writing style will flow well and be easy to work with! This would be 30 hours altogether, however, I would probably proof-read, edit, etc, in large stints, say 6-8 hours per stint, 2-3 stints every 48 hours.
This said, I estimate that I could have a the first fully proofread/edited copy back to you at around the 3 day mark, which would give us 2 days to further work together on making final editing processes, making sure we're both satisfied, etc.
Over the past 2 days I've done two articles/reports, and one website proofread, with excellent feedback. For two of these customers, I'll now work with them quite regularly as they were that satisfied with my work.
If you have any more questions feel free to message me, and I look forward to hearing you, and potentially working for you! :)
Thanks, Anthony.
