Metrocast, the cable provider, will likely get you the fastest service at the highest price.
TDS, the telephone provider, offers DSL at most locations, they were advertising fiber, check with them, this would likely be your most cost efficective solution if it is available at your particular address.
Cell companies, are ok for the light/occasional user, don't try cutting the cord and relying on this. (my opinion). You are lucky to arrive after the new Alton Bay cell tower is up and running
That is about all the providers, I am aware of, in that area
