The problem is, if you know enough to know what to ask, you know enough to start performing the treatments yourself. But then again, I can certainly understand not having the time and wanting to hire a contractor. As an example, I can work on cars, but that doesn't keep me from taking mine to the shop. But I can instantly tell when the shop is floundering or bluffing, and that helps me find and maintain relationships with good mechanics.
I suggest looking through the links in my last post and reading some of the material here and elsewhere. In my opinion, you should try and understand acoustics well enough to know the basics of what needs to be done. Otherwise, you just can't tell the snake-oil salesmen from those with a real understanding of room acoustics.
