Found your post-project debriefings very interesting to read, thanks for documenting your experience so thoroughly.
If you don't mind, I do have a question: what did you do in terms of the legal side? I.e. did you start a new company for each month, do each within an existing corporate umbrella, or just not worry about that until you needed to? Or maybe something else entirely?
I was about to give up and get a day job.
