You stated the problem. Now to wait for the lines to thaw.

Any plumber or well company can fix it.
First thing I think I would be looking at is the check or foot valve. If it's bad the pump looses prime.
A crack in the suction line from freezing can also cause it to lose prime.

How deep is the line from the cistern to the house, and how long is the run?

I am not sure how to check any of these things, I can tell that the pump is at the bottom of the tank from the outside, which appears to be about 15 feet underground. Should i be ripping apart walls to find where the line comes in? If the problem is the pump or piping at the bottom of the tank is there a way to get to it to fix it? I am not even sure how I would drain it since I can't pump water out of it and into the house.

That is because the line is frozen. Walk a straight line from the cistern to the house, and that is probably where it enters.

In the absence of knowing where the line even is, I'm with Joe in suggesting that you call a local plumber or well driller. They should be able to lcoate it and apprise you of your options.
