2. Perform a survey and put out a press release on the results. We just did one recently on the real estate industry here: http://kirstydunphey.blogspot.com/2008/09/real-estate-agents-trustworthy-is-new.html using a free online survey program and having 500 people respond. The results give journalists some statistics to work with and help get your name out there when you're published as a source.
