Need a guesstimate please.

Before I get a local contractor over, I was wondering what it should cost for materials to put up a deck fence. I measured the existing wood fence which comes out to about 75 feet. I also have two stairways. I want to buy pvc, 4' high, nothing too fancy. Can someone give me some idea of what I would need and how much it should cost me in materials only, this way I can gauge the estimates I get. Thanks in advance
