I just could never see the justification of running a yp ad. Since most (VAST majority) of my business is clientele based-repeat customers anyway, there's never any need - our work is our biggest advertisement. As it is, I already give ridiculously high qoutes sometimes and STILL get accepted!Now, if we were doing something like just installations, or just sprinklers, or something like that, that is a one time deal, then I could see it. But if I want more commercial work, then I go out and bid it. If I want more residential work, then I target an area. But if I want my phone ringing off the hook everyday with people asking me questions like; "How much do you charge to mow a lawn?" then I'll run a yellow pages ad.
