Studio layout/Cost Questions

I am currently looking at leasing a commercial space with a friend in order to build a studio. I have read through most of the references pages in this forum, and I now think I'm ready to start asking some questions. Please forgive me if I did not research well enough. I have attached images of the floorpan, as well as my idea of what should be done with the space. I don't have access to or know how to use the fancy CAD type programs, so I went with illustrator. My design is very rough, but it should give you an idea of what I'm trying to do. We would like to keep our total costs to $20,000 or less. We can do some of the work, but most of the major construction will need to be done by a contractor. If you think this budget is doable, please say so. If you think we're crazy, please say so. The space that we are looking at is on the end of a row of office suites in a one story building. We would have neighbors on one side and a parking lot on the other. The suite currently has a combination of carpet and tile on a concrete foundation. I do not know for sure, but I believe the suite has a ceiling that is between 12 and 14 feet. It is hard to tell because each room has a dropped ceiling. The two large rooms near the rear of the space are what initially caught my attention. It seems to me that the current layout provides great "shells" for the main tracking room and control room. The other two rooms in the front left of the property look like perfect candidates for a small "B" control room and tracking room. Below are some of my observations and questions about the space. 1. After reading through the posts on wall construction, it seems like the first thing I should do is reinforce the wall that connects this suite to the neighbors with a couple of layers of drywall, the first layer vertical and the second horizontal, utilizing the techniques described in the reference secion. The current wall is paper thin. When standing in the "lounge" I can understand everything that is being said next door. However, the rear of the building seems to be a little better. 2. I based the control room design on the control room we currently work in. The room was designed by Russ Berger about 8 years ago. The people who own the space need to use the space for other purposes, so that is why we must leave. Fortunately, there is a good chance that we will get most of the fittings for free or at reduced cost. I worked the double glass window and steel door w/window into the current design. The room we are in now is more narrow from front to back, and I am unsure of the exact dimensions. My control room design for the new building is "fatter" and more square-like. Is this a problem? Opposite the double glass window is a sliding glass door that leads to the machine room. How important is a floating floor in this room? We will be using near field monitors and we listen back at moderate to low levels. If we extend the control room walls to the ceiling, what type of ceiling should we use. Is it even necessary to extend the walls to the ceiling? 3. My guess is that the tracking room will be the big expense. My guess is that extending the new walls as well as the existing wall will be quite pricey. Should I remove the drywall on the inside leaf of the existing walls in order to achieve the proper mass-air-mass system? I'm not terribly concerned with having perfectly isolated rooms. My main concern is limiting the noise to our neighbors. I can live with a little outside noise as well. How vital is floating the floor? Is the expense and time worth it in this situation? 4. Isolation in the "B" control room and tracking room are not as important. The only plans I have for those rooms are extending the tracking room and building in an iso booth and storage. The main reason for the storage area is to close off the large window in the corner. Thanks for taking the time to read this. I've attached pictures and floorplans that will help you better understand the space. Any help will be greatly appreciated. Jon

Jon - you are going to be pushing it to do this for your stated budget - but your layout is well done :) I've only this option to add. cheers john

thanks for the idea. I will take that into consideration.
