For what that guy will spend in that, that is just crazy. But still a
good idea non the less. Here's the solution...

Two - Way Satellite Up and Down. There will be at least a half a second
delay. The OP will be able to stream the FM signal to the Web his self
with his own server. He can take a direct AF[1]output to a sound card
input into the server from the FM transmitter. If the OP runs the
station he will know what an AF[1] output is and will need an attenuator
between the two. There are a many Linux Apps that can pickup an
AF[1]audio output into a sound card.

The only drawback to this is the Sat Connection cost fee per month.
Being this is on a "indian reservation" I would seriously look into
government grants for this if I were the Project Manager (technology
grants).  The only company I really know is Motorola that can provide a
hardware solution for this type of solution.

1- [AF] audio frequency
