Setting up a network on a large scale: Cost?

[Viridis]

For Technical Writing we have to come up with a proposal to give a fictional committee. My group is talking about revamping the internet services for a dormitory. The walls are too thick to make a wireless network viable so I'm thinking of wiring the entire building with an ethernet network which then connects to the internet source.

Anyone have ANY idea how to estimate how much this would cost? How high-end does a router have to be to handle over a hundred users? I also have no idea how to estimate the cost of labor. :stressed:


The numbers can be mostly complete guesswork because the teacher isn't checking up on them, but I still don't know where to start. Can anyone help?
