Basically, DSL will only work for about 18,000 feet from their central office, which is in downtown Meredith. This is feet of wire, and there can be no intervening equipment (such as SLICS) in the way. That would eliminate DSL as an option for you.
DSL gives the best price performance (if you can get it)
Cable gives the best bandwidth performance (actually, FIOS does, but its no where near this area) tho its slightly more expensive, but generally less expensive than those below.
If you can't get DSL or Cable, you can try getting a data card for your cell phone, tho I understand their 'unlimited' plans are not unlimited (for example:
http://www.consumeraffairs.com/news0...unlimited.html )
OR, you can check out the classified section of this website, and there is a wireless provider in the area
Last, but not least is satellite internet, offered by the NHEC. Very expensive up front, throttling and latency issues, but if you can't get any of the aforementioned, its an option.
