Traffic Beast - Do Conference calls on your niche
I make at least two or three E-book sales after most of my calls. It may take some time to build a following, but eventually people will know the value in coming to a free live phone conversation about something they'd like to learn.
I have them on high performance entrepreneurship, which totally interests people.
This site above is a great resource. It's totally free (like.. literally, free), you get to control, mute, record and store all of the calls and they even give you a number to call and a code to give your attendees. It's absolutely one of the new ways to do great on the net.
