Making a Roadfood TV Webcast profitable.

This question may not exactly fit the forum I'm posting it in, but I'd really like to get some feedback from restaurant/food service professionals before I take it any further.
 
In my spare time I operate a small video production company. It's mainly a hobby, but also a growing secondary source of income. I am very good at it and can produce network-quality content. Lately I've been toying with the idea of producing a roadfood travelogue-type show for webcast. It would have a TV show format similar to DINERS, DRIVE-INS, and DIVES (but without an on-camera host - it would have a voice-over narrator instead), and would feature locally-popular mom and pop places with interesting menu items. Actually it would be a lot like the FOOD PARADISE series in that each episode would spotlight a particular type of food: Burger joints one show, Hot Dog places the next, BBQ the next, etc.
 
My biggest dilemma is this:  Since it will (initially, at least) be only a Webcast, and a decidedly region-specific show  - mainly centered on places within the Tennessee Valley (Northern Alabama, Middle Tennessee, and Northeast Mississippi) I'm not sure how to make it profitable.  I could self-finance the first couple of episodes as they'd serve as a pilots/proof of concept, but after that I'd need to start making it pay somehow.  
 
Any suggestions?
