On your second point about using acoustical panels, this may be an option as I will need acoustic treatments for the room after drywall anyway. I understand that ideally soundproofing and acoustic treatments are different animals but if there is overlap between the two and since I am trying to save some $ could acoustical panels work for both? Thoughts?
I am not an expert but am looking to do what you are trying to do with more $$$. Now if you do not have finished walls, you might want to create a room inside a room with no clip, no channel, just a second wall and ceiling not touching the current wall and ceiling. You can still put 2 layers of drywall to this new wall (on the inside part). Check http://www.soundproofingcompany.com/...within-a-room/
. As soon as you add green glue, channel, clip, the price will start to rise. I think a room within a room with basic stud framing (no premium stud), 5/8 double layer drywall, big box of drywall screw long enough for both layers, everything bought at a home supply store and not HD or lowes, you should be way less than $1500. Now when you add the cheapest fiberglass insulation R15, you might be above $1500 for such a big room. Same buy the insulation from insulation suppliers, half the price than HD in general if you can pick up the material at their warehouse. One more comment, for the framing, go visit the current homes under construction at the framing stage in your area and ask the guys for framing your room and say you pay cash. You should find some guys that will bring the nails, the man power, the tools, and maybe the studs for cheaper than you can buy the studs at HD or Lowes, maybe not but close to. There is always leftover when framing a home and they can use this leftover in your room.
Last point, for the floor, you have to check how it is done, I did not as I will not go this route.
