Treating my control room with a pitched ceiling

Hey there....I have come to the point where I am looking to treat my control room. I have moved into a place where there was an addition built onto the house with a upper and lower level that I have decided to use as my studio area. I have read alot on how to build panels etc but I am needing some guidance on how to treat the room to get a decent mixing environment. Noise isnt that much of an issue but quieter is better. I am not wanting to do any major reconstruction but want to have a good mixing environment. My budget is $2000 ...$3000max i guess The top room is 23' long by 15'7" wide with an pitched ceiling that is 8' high at the outside edges and peaks at 10' running lengthwise. The walls are untreated and is normal 5/8" drywall with standard fibreglass insulation. The room is square so there is 2 sets of parallel walls. Also on the back half of the ceiling in the middle there is a skylight. The rooms are connected by an open stairwell which will be framed off. I have included pictures and a layout with measurements to help out. My main questions are : what should I do about the pitched ceiling....do I want to make a floating ceiling, or hang a cloud or multiple panels from the ceiling? or make one side of the roof steeper with a "fake ceiling" do i need any diffusion on the ceiling? where do i need diffusion on the walls? I know that there should be absorber panels in the corners to act as bass traps and around the room to minimize first reflections but after that I am not sure where to place more Altogether I'm asking how I should go about treating the room and designing it to have the best acoustical performance without any drastic construction.

hey cmuller whats up, just to let you know before some else tells you... you should resize your pics, making them easier to see your problem, take care Ensonix Studios

hey thanks...that should be better now i think

i would just put up a cloud over the mix desk, one at the peak, and one on the back sloped ceiling. that should give you decent control.
