Pick and research your topic. Some topics have more profit potential than others. Weight loss and home businesses are two of the more profitable broad topics but you can make money in many niches. Know your audience and how you'll reach them before writing.
Write your booklet. Compile all of your gathered knowledge into an information-packed 12 to 32 pages. Booklets of this type are often called "special reports." Be sure you aren't writing fluff. It all has to be meat to be worth someone's money.
Print your booklet. Since booklets are all about information and not aesthetics, you can use desktop publishing to print and staple your booklets at home. If you plan to have your booklets professionally printed, have them printed in bulk through an offset printer like gotprint.com.
Set up a website and a shopping cart through e-junkie.com1 to process orders. Be sure to add shipping and handling charges. This is especially important with lower priced ebooks if you want to make a profit. With higher priced ebooks, it's personal preference. You'll make more profit with shipping and handling added onto every booklet, but you may sell more higher priced booklets if you cover shipping yourself.
Advertise. Drive traffic to your order page through online grassroots marketing efforts such as social networking via Twitter and Facebook and participation in forums related to your booklet topic. Advertise in online newsletters that cater to your audience, or in the classified ads section of print publications.
