I have a domain name, a salespage written by world class copywriter and an ebook written by a millionaire.
I will pay you whenever 1000 people download the ebook, which is FREE.
You can drive traffic in any way (even by telling your friends to download the ebook), just not spamming unknown people. So please bid the amount you want to get paid for 1000 downloads.
I have an account management that keeps track of downloads (even hits and other detailed traffic statistics). This is not my webhost stats, but specially created to track downloads.
If you have any questions let me know. You can suggest payment options, but I usually pay via escrow.
