Yeah I understand the point regarding drilling, etc.
We've had to make a bit of outlay initially in terms of buying kit to do it. My regular toolkit including Dewalt SDS, Long Masonry Bits, Trunking, Screws, Rawl Plugs, Drums of Cat5, Punchdown/Crimp Tools, etc.
Was worth it for us as we did a total network rebuild last year as soon as I had the ability to correct years of previous underinvestment and reliance on county ICT advice (you all know the story...) With the help of 3 other guys we managed to get the whole school rewired with new cat5e everywhere. Now got 7x 24 port switches. Not bad for a school with only ~270 pupils
As for fibre - I totally take the point on that one as well. Fibre is obviously a lot more strict when it comes to bend radius' etc, and having someone who really knows what they are doing with it is advantageous. As for us, even our backbone runs from switches to server room are all less than 100m so its just 2x 1gb trunks which does the job no problem.
