In a nutshell, some D.C. lawyer is making good money but setting up lawyers with potential partners. First of all, this is an amazing business venture. Second, this is really sad. The unfortunate truth is that law school and the law profession take up a lot of time so there is a market opportunity for anyone willing to set lawyers up on dates if they know what lawyers want. This attorney apparently makes good money but acting as a professional match maker.
But why the need? Here are some numbers from The American Lawyer:
Associates Wachtell, Lipton, Rosen & Katz worked on average 71.1 (and billed 62.5) hours per week [in 2005].The Avery Index does some math to show that makes up more than 60% of a waking-week.
Some of the prices the D.C. attorney charges seem a little high, even for a lawyer. Fortunately you can find some helpful information on how to date a lawyer. Might I add that you should read his blog.
