Depending on where you are looking, and what your budget is, and your level of motivation you might look into seeing how difficult it would be to build your own point to point link back to a place where you can get 'real' internet.
I also want symmetric gigabit but in a very rural location I might be totally satisfied with 40 Mbps down x 15 Mbps up, if it was sufficiently reliable and good quality (overall uptime in a year, latency, jitter, etc).
There is a great deal that can be done with sets of equipment like a 90cm high performance dual polarity shielded dish (ALG or Jirous or similar), ubnt AF5XHD radios, etc. Perhaps for less than $10k all-in you might be able to build your own link to reach the nearest WISP or terrestrial connectivity. Entirely depending on how remote you are and terrain.
But there are also vast areas of Idaho too sparsely populated to support any WISP at all, where you'll see cheap consumer grade VSAT stuck to the sides of peoples' houses.
