There are lots of older private label rights ebooks available for free or very cheap. You could do some massive editing, add new graphics and a new sales letter and have a product but there is an easier way to re-purpose these into a profitable form.
First do the keyword research on that topic and find the best buying keywords. (This is something you should be doing for every project.) If you are not sure how to do that check out the keyword research call.
Find a minimum of 3 or 4 good affiliate products you can promote that match that topic.
Take each chapter and create a quick article slanted towards one of your keywords you created.
Now each of these can become part of an ecourse. Create a squeeze page to give away the ecourse and build your list. Add an affiliate offer to each ecourse lesson as a ps where appropriate.
Now submit the articles to various directories to drive traffic to your squeeze page. This allows you to build a list and have an automated income source easily.
You can take it to a higher level by adding a blog and using your articles or versions of them there before you submit them to the directories.
These are easy ways to take advantage of some of the dust collectors on your hard drive and create a hands free income source with a small amount of one time effort.
Now go do it.
