I got a manuscript to review, so this is a good test of how long things take. I read the book, about 250 pages, in 2 1/2 hours, so I read at more than 60 pages an hour.
I wrote most of a report (1000 words) in another hour.
I will need another hour to write the rest of it and revise and polish it to make it very good and carefully worded throughout. I work fast but I want the report to be super impressive, as though I had taken longer. I will wait another week before sending so people won't think I'm being too hasty. Also, then I can look it over again and make sure it is all good.
So the whole process will take 5 hours, making my rate $50 an hour.
