Yes. I take couple Wikipedia articles, copy-paste in msword and rewrite sentences. Take 3-4 hours max to get 10-20 pages.
As long topic is on Wikipedia I can manage with no problem. Sometime there are strange character pasted but msowrd fix it for me by highlighting them.
3. It is obvious that any research time is time not spent writing, and therefore time when you're not making money.
My Internet research methods are very basic. Research is no problem - people that post in Wiki do research. I do re-writing.
4. What quality do you generally aim for?
I set bar low as possible coz I pay by word count. My computer memory buffer is always full from Wiki paragraphs. To get one page quickly, I copy few paragraphs and then rewrite them so it look not 100% plagiarized. It look 30-50% but I tell client it's plagiarism software problem or that I use many citations. Many believe this story but some do chargeback.
