That is it. The question alone, for now. All readers should feel free to comment. Especially if having an educated guess as to any other million dollar consultancy.
Comments expressing a guess are particularly welcome between the initial posting, and the UPDATE. And, what's an update without a spreadsheet? Answer: an assertion without presenting the evidence.
El Tinklenberg dba "The Tinklenberg Group" invoiced and received $1.1 million from early 2003 to the present. And there IS spreadsheet evidence, per this Crabgrass post.
