Great to see you haven't fallen by the wayside! I remember being impressed with the original information. Could you refresh my recollection of where you will be shooting and/or are you building your own sets? I like the fact that you are waiting on the script before committing to anything else. My own suggestion is to send that script through the meat grinder several times and then maybe ask for help from someone outside. There are several professionals posting in this forum and they might be willing to help with it. I am definitely not speaking for any of them and won't name....if you post regularly in this forum, you probably have a good idea of who they are.
Best wishes for a great project!
