OK, I've heard of cutthroat competition, and I'm not that scared of lowballers, but this goes beyond what I ever imagined! Last season I was putting up signs in certain area of town, just focusing on one area, to be more efficient. Well, I advertised for $30, and had plenty of business and this new guy came along and started putting up signs everywhere for $20. I didn't even change my sign, but I ended up finding out who he was because he actually called me to do some jobs that he either didn't want to do or didn't have time to do, which I took, because I had some room on my schedule. I ended up breaking my collar bone in an accident, and that pretty much ended the season for me, unfortunately, because I had no help. So this season I lowered the price on my signs to $25, not planning to do anything but the smallest yards for that price, but I didn't want my competitor to get all the calls. Today I got a page from him, and he started asking me why I put signs in "his" neighborhood, and acting like he owned the whole neighborhood, and couldn't believe that I was putting up signs there after he "helped me out" so much, even trying to say he taught me stuff, although I have much more experience. When I responded by starting to point this out, he threatened to break my other collar bone! He said "You better watch your back when you're going to give an estimate and you go in the back yard, cause I may just be waiting..." I told him I was going to call the police and he hung up. He then left messages on my voice mail cussing and saying "Don't put your signs in my neighborhood and we won't have any problems..." Who does this guy think he is? The mob? I never expected to have this problem but how should I handle this? Make a police report? I'm not going to let him tell me that I can't put my signs in his neighborhood! That's ridiculous. I was putting signs up there years before he ever came along, is the irony of it. Any suggestions?
