First: I wonder how much footage we could acquire from other teams. It might be road footage, but if the Yankees have a ton of it, we should be able to get some. This is also the day and age where people are finding things in attics and basements. Throw out some offers to fans - trade footage your family may have for some seats - club, suite seats, a team meet and greet. Same for the Bulls and Hawks. Hire a media person specializing in that to assemble whatever they can and then assess from there how much they have acquired.
Also, another option is to throw on some games from local teams in the state. If their games aren't being broadcast elsewhere, throw on some of them.
