OK, my turn to chime in with the paranoid voice, as I usually do in these kinds of threads.
If you don't know what you're doing and don't have the proper equipment to certify the cable plant as fully compliant and error-free, you shouldn't be doing the job. ESPECIALLY for a friend.
Businesses these days live and die by their networks. Cabling problems are one of the more common network problems and by far the most difficult to diagnose - After all, it's just a cable and it works, right? Something simple like a cable run to the server (or even to Bob's desk) that isn't done right and is causing occasional interference is VERY, VERY difficult to troubleshoot and can have drastic effects on the ability of a business to function. Take down Bob's computer and he can't do payroll or pay the bills and you've got very, very bad trouble.
Don't take this the wrong way, but cabling is something you should leave to the experts. They do this for a living and have $10K+ testers to certify a cable plant as being compliant and error free. They also carry liability insurance and understand how to write a contract to relieve them of liability when they aren't responsable.
I'm sure you're a competent cabler. But what happens IF something goes bad and causes the company signfiicant monetary damages? Are you carrying liability insurance for this kind of thing? How about your friend, who picked you to do it and it's his responsability? What happens if your fishtape slips and shorts something out that you are responsable for paying for?
Yes, you're probably going to go ahead and do it, but just keep this in mind. Be SURE to get them to sign something that says you're not responsable for related problems down the road, and especially not damages due to related problems. And triple-check everything.
