I'm in the same situation as you, no other choice for internet since neither Time Warner or CenturyLink seem interested in serving our area. And we've got way more than 10 houses out here. Less than 5 miles from downtown (small town, granted but still) and there are about 55 houses in the 2 miles between my house and where DSL and cable both stop.
Fortunately, I got on the Sprint unlmited plan for my broadband card about 5 years ago but the speeds have gotten so bad it's unusable most of the time. LTE is on the tower but I can't pick it up on the phones at the house (at least until LTE800 comes along).
Since I work from home, I got an AT&T hotspot for the LTE speeds with the 5GB plan which is about $38 with my work discount. I got the hotspot outright and am not on contract. But at least the overages are only $10/GB with them. Verizon has larger plans available if you're in their LTE network and they even have a Home Fusion Broadband service that gives you 30GB for $120/mo. with $10/GB over (or maybe $15).
The good thing about Sprint's plan is that you get 12GB for a decent price but the overages are unacceptable. At their stated 5 cents per MB that's $50/GB. That's just insane and it's something I hope they change soon.
The newer satellite plans are also around the same price as the Verizon home fusion, about $120 for 30GB. And sometimes you can get additional data in off hours if I remember right. And overages are around $10/GB. It's been a couple months since I've looked though.
Rural customers just don't have many "good" options for a family that wants internet access. And with some of the charter and magnet high schools now requiring high speed internet access at home to be considered for enrollment we're at an even further disadvantage.
I'd look into the Verizon Home Fusion if it's really for home only use and you don't need to take it mobile.
