There are several ways: try being a volunteer key speaker at a trade conference. I, for example, will be doing a presentation at a Marcus Evens conference. They're waving my fees and covering my flight, but I still cover the hotel and food...but there's 50 top and upper executives in front of me for me to show off to.

Try a webanier...that may be a mixed audience but if its good and you're doing a series, word of mouth will spread.

Get on a radio show.

The idea of the articles is not bad, use the other platforms to meet and then personally solicit help directly, while still at the conference. There is always a meet and great time.
