How much will it cost to set up a tv station from a sattellite and broadcast around the footprint?

You can look into getting your ham license. Then you can work slow scan tv or even fast scan but only on the ham bands. On fast scan you can link up through satellites. A ham license cost you nothing in the USA except a small fee for the test usually under $20.00. Unless you want to be a full Commercial station. This might meet your needs.
