Do you use sites like mediabistro.com for leads/ideas/names?  If you're not having luck, revisit the networking contacts -- give them an update on where things are at and ask again for their help. Many times they know new people to connect you with.  Cold call some of the media heavyweights in your area and ask them to give you 15 minutes of time.  Explore various aspects of media: it could be public relations, it could be writing for a magazine. Don't leave any stone unturned!
