I've been scammed handful of times on paypal while trying to sell eBooks...these low IQ apes ..they saw "it doesn't work for me" "i didn't recieve it" "not as described" etc etc.
So, I figure why not get something like Adobe Acrobat or any kind of PDF editor, go on amazon associates and or clickbank (any kind of affliate website) and just link the affliate links to any related words in that eBook you have. If you have a squeeze page, I'd recommend you link it to that too!
So you basically give these ebooks for free.....people read it ..they won't complain BECAUSE they got it for FREE ...if they click on your affliate link(s) and buys you make a % of the sale.
As for traffic, I recommend you make reviews about your ebook and post on youtube.
Add my skype if you'd like and we can discuss a bit more
