basement studio construction

OK, so I'm planning a room. It's a 15x30 basement room. Along the 30 foot length, there are is one HVAC duct on each side running along the ceiling with vents into the living room above. I have the ceiling pretty much figured out except how to deal with these ducts. I have other ventilation plans so I won't be using them.

Thougth you could perhaps assist me, what i currently have is a laptop, mlx mic, m box, electric kit, drumkit from hell sample and a guitar of course.

What i need now is for you good people to tell me what equipment i need to achieve this kind of sound:

I am located in southern massachusetts and in need of a contractor for my basement studio. I tried Owens Corning but they seemed to sketchy considering they cancelled the appointment like 3 times. If you are a contractor or know of one please contact me. It would be a great help.

Thanks,

I'm in the beginning (planning) stages of building a basement recording studio and was wondering on about how much power would be needed to run a small studio. I know its a very vague question but i am just looking for an estimate.

Thanks,
