I currently help out at a network that only has four hubs.. them being their main channel, gaming channel, music, and media channel. If you're interested in talking to them I can PM a link to their site.
The only reason I suggest that route is because to form a network you need to become a CNA(Content Network Aggregrator) which you must do with BroadbandTV or another network. Then if you get approved and accepted you have to make a binding contract which I'm sure requires a lawyer etc. It's a real pain in the ass and it takes a lot of time and money.
