There are three companies that you can send room diagram to and they will suggest room treatments for your room (that they sell).
1. Echo Busters: it could run you around $4000
2. Media Specialty Resources: they have several levels of pricing but I think they are more expensive than Echo Busters in the end
3. Auralex Acoustics: it could run you around $4000
If you don't have a rectangular room, then I don't know if you will be able to figure much of this out on your own. Even if you have professionals coming on site taking measurements and such, the outcome won't be as good as if your room is rectangular to start with.
Keep us posted on the results when you actually start putting them together. This is something that I would like to do sometime down the line. I've only been lightly researching this.
