How will you ever learn, grow, expand your skill sets? I had a teacher for industrial wiring once tell us " One day you guys are gonna learn that you can make a lot more money running little tiny wires than big hulking fat ones" and he was right. I hear that many data companies charge upwards to 300 bucks an hour doing data work,cat 5 punch downs.
But if you like playing it safe then dont do it. And Im sure there is going to be at least 50 guys in here that will try to scare you into not doing it and making it sound like rocket science. I did data work for a while when I was working for someone else a few years ago and its really not that hard. Just do your homework before hand.
Personally, I hunger to learn and do new things all the time. Do you really think I want to cut in high hats and outlets my whole carrer? I mean if its something that you honestly dont even have a clue as to how to do, than dont do it, but if your just talking about patch panels and puch downs its really not that big a deal. I dont know how big your company is but maybe you can ask your guys if anyone wants to specialize in data work and you could make him your go to guy. Send him to school to learn more about it.
All I know is here in North New Jersey resi and commercial EC's are a dime a dozen. You need to set your self apart from the rest IMO, and make your company more marketable in the long run.
Anyhoo thats my two cents.
