Flight Simulator Cockpits

Hi guys
im new to this site but have been reading the posts and am very impressed.  I am new to building a home cockpit but am well experienced with FS.  I am also experienced in woodwork and electronics.
In short i need help with how to get switches and stuff like that interfaced with FS.  Also how to set up a multiple pc network to run the screens.
I am looking to build a civil airliner type cockpit.  My aim is to do this on a sensible budget, therefor what i am trying to offer is a decent cockpit that isnt true to any one aircraft but can be used for many.  I this this could be beneficial to many other first timers.
Any help would be greatly appreciated.
Thanks Jake
