The only real option is to get them to come out and officially take a look at your house. Tell them you want to know the cost of getting service if service is not available.
That will give you a starting point. If they come back and tell you it will be $50k, then you know its not feasible. If they come back and say $5k and you have 19 people willing to split the cost, chances are they will pick up a good portion of that cost.
But the first thing is to get them out with an estimate so you know what you are looking at.
