$5 or $500, at least this academy recognises that the best person to write the whitepaper is the project owner. There's no substitute really. Of all the things projects outsource, the soul of the project is one that shouldn't be. Hire someone to edit, clean, tidy up, sure. Another to create marketing one pagers and presentations out of it, of course.

But no, never to write your whitepaper. Would you outsource deep sea diving and brain surgery if that were your profession? (To use the examples on the website itself).
