Need 100 Reviews for a book on amazon

they need to be from real people. diff ip addresses, and need to have physically downloaded the book before placing their short positive review. Any idea how to do this, and potential cost? thnx

This will be difficult. I know of someone who tried doing these themselves for a physical product. Blocked/different IPs, etc but Amazon caught on and deleted the reviews. You are right that it will need to be real actual people.

What you might want to do is offer the book for free in return for a review. And pay a blogger to post about it to his readership.
