As somebody who used to work in quality assurance for DirecTV, let me second the notion of telling them that it looks like you are going to have to go with whatever cable company serves the area. Doesn't matter if there are no lines there, DirecTV doesn't know that. DirecTV trains their customer service to transfer to their SAVE group (customer retention) at the mention of leaving DirecTV for cable. That group can get some magical things done and I would be surprised if they can't get you an installer out there within a few days.
