Internet service options for outlying area?

I work for a NPO, the internet access at our youth camp in Palestine, Texas is via satellite and painfully slow on its best days. Its better than dial up I guess but not by a whole lot. None of the local service providers extend out that far. Internet access from any of the mobile companies like Verizon or Clear won't work either, we tried it and it didn't get any signal at all. Does anybody out there have any ideas how we could get better and more reliable internet access in a area like this?
