The best thing you can do is become the best at your trade, and teach your techs how to follow a system to become successful and remove room for error. At my company our pay structure is setup in a way that they are paid percentage points for following certain guidelines and procedures. If they don't follow these procedures they wind up docking their own pay - which quickly teaches them that doing it the way that I've created is the way it will be done. I have weekly 1 on 1 meetings with each technician to review their #'s, review their bonus tiers and make sure they have everything they need to be successful. We set goals for the next week - so that once we get to the next week we have a pattern we're following for steady improvement. (Reducing call backs, increasing a certain sale, earning more raving reviews etc).
I've done it both ways, working my ass off out in the field cleaning carpets - and working my ass off in the office. Both are challenging, but I would rather be in the office leading and coaching then be stuck out in the field where I'm only able to work on one element of the business.
