There's an Australian company called KordaMentha that specializes almost exclusively in bankruptcies. (Or, at least to us laymen, never makes the news for anything else.)
Funnily enough, Korda Mentha came into existence as a result of two (or indeed, three) giant corporate collapses, one being Australia's previous second airline.
When Ansett Airlines went into administration in 2001, Arthur Andersen was appointed administrator, and Korda and Mentha were the partners put in charge of the business.
Then Arthur Andersen was forced to shut down as a result of its part in the Enron collapse, so Korda and Mentha started their own firm to handle the ongoing Ansett work.
