.. when Dennis Lively was starting up his radio program at
http://www.netbizradio.com - I'm fairly sure he started promoting his first guest(s) well in advance of the launch date. Creating a buzz about the first program and future guests will naturally give you good press release material.
It might be nice to interview Dennis Lively himself about the energy/finance/effort required to start up a new program.
... I'd really love to hear an interview with Gordon Jay Alexander and Dien Rice, Cornell Forden, Dennis Beavers

...... Donald Trump!!!!!!!
Best wishes to your success.

.. btw, there are Many experts here who would make fantastic interview guests - I didn't mean to offend anyone not mentioned in the list above, just thought I'd start the ball rolling!
