Need to extend an ethernet LAN over phone company wire less than mile

I am not very familiar with all the terminology. I have two locations less than a mile apart in a rural area. I assume the phone company could (if I knew how/what to ask) make appropriate splices to give me two or more pair of copper between the two locations. Is that what a "leased line" is? Or does that go through the exchange?

Assuming I could get this copper between the two points, how fast could I send data between the two? I have an ethernet lan on each end that I want to connect together. And of course :-) I want to do it for low cost.

I would simply use the internet but there is no high speed available out there in rural Western Washington State.

Thank you all very much, Harvey.
