My competition comes in a few shapes and sizes.
The "annoying" competition is a bunch of Yamaha club series speakers, and a pile of mis-matched gear from the early 80's/90's. He underbids everyone, sends out crappy crews and honestly, I'm surprised his gear hasn't burned any venues down yet... He's the kind of guy that can send out 5 systems at a time, and yes, they make noise, but my god it is just not pleasant. The only reason he stays in business is because he can do so many shows at one time.
The "real" competition is a company that doesn't always underbid everyone, but rather, they just have a lot of idiot techs and poorly deploy systems all the time. They've got some big accounts in the area, and a lot of gear. I'm slowly stealing away some of their clients, but it's a big work in progress.
The "rest" all have an understanding with each other. We help each other out when needed, we stay out of each other's hair, stick to the same clients, don't try to steal anyone away from each other. It works out well- there's probably 6 other companies in my area that do a lot of the same type of gigs I do, but we just leave each other alone. We are all busy enough that we don't need anymore of those types of gigs. I'm the "largest" company in the area at this level, so people really don't mess with me.
