I wrote one about a year ago for a company that was in a space in which I have experience and who found me via a mutual contact. They paid me $5,000 for a 3,000 word whitepaper. Ultimately, it took me about 40 hours of work, between the initial meeting, emails, research, writing, and later updates (so about $125/hr). I probably wouldn't do it again, as it was more time consuming than I planned, but I did learn quite a bit about a niche topic.
