First let me say that I love Debussy, and this would be a great project to work on.
But what is your budget? I can produce work like this, but it's very expensive. Working with many content projects the biggest problem I encounter is that clients are not aware of what standard production costs are. Clients constantly drop 5-10-20k projects in my lap, and ask whether it will cost 200 or 300 dollars.
Assure me that you are serious, and I'll write you up a quote and send it. (for frame of reference, "will you do a 10k job for me for nothing+exposure" is not a serious offer)
Renting a second camera and 3d rigging alone would cost at least 2500 a day. Do you require 3d CGI intros, credits? Is your stage well lit already? Will you pay transportation costs? What is your target quality, television, film, local broadcast?
