Marla,
If you have very specific requirements, you might consider hiring a carpenter to build it. I did that in the backstage area of one of the schools where I taught, and it worked out really well.
I see that you are not but 17 to 18 miles from the Olney Theatre Center. You might check to see if their Technical Director thinks their stage carpenters and apprentices have space in their production schedule to take on the job. When my son worked there, they did a few jobs for other theatres. Using carpenters from a professional theatre, you can be assured that the cabinet will be sturdy.
