I'm pretty sure you should check with the cable company before you decide your house is too far from the road. My dad is a general contractor and we build houses all the time. I can think of at least 4 occasions where we called the cable company to have wires buried to the house. They have to do it if you want their service, and one time it had to go over 2 miles!

As far as amplification goes, you would leave that to the cable company too.

Your idea of using wifi is a good one, however you will need more than just a high powered access point and large antennas. That 1500 feet you mentioned is in a circle, not one direction. You would need a repeater to re-send out the signal towards the edge of the "bubble" of wifi access.

Hope this helps!
