拉線 Lan/ Phone

my office will move, need find someone to 拉線 for computer/ PBX phone system...

I think it may need the wall plug with 2 RJ-45 , 1 for Phone, 1 for Lan.

it may need 80 plug in each staff and need someone to handle the 拉線 from my NEC PBX system to the server patch Panel with 內線#.. mean he must know how to handle my NEC PBX phone system.

any idea or which one I can find?
