Legal question about Internet?

My parents live in a rural area of West Virginia on top of a mountain... They currently only have access to satellite or dial-up Internet. The company that has rights to the area has tried several times to install cable lines up the mountain in order to allow high-speed Internet and cable to reach my parents and their neighbors (about 100 people in all). One man who lives at the bottom of the mtn refuses to allow the cable company to install the posts needed to run the cable. Everytime they set the posts, he digs them up or cuts them off in the middle of the night. Several people have tried to talk to him with no resolution. The cable company says that they looked into burying the cable but there was a problem with that and it will not be a solution. I know that there is a law that even when you own roadside property a small amt closest to the road is still owned by the state, the problem here is that the bank is drastically sloped and the posts do have to go onto the man's property slightly. The man is demanding $25,000 to install 3 posts on his land as well as a monthly fee. The cable company is refusing to pay, therefore my parents and their neighbors are left with the headache. Anybody have any ideas of what can be done about this?
