This is what I do when I am consulting.

 After looking over deep documentation, examining inventories, interviewing key management, poking around the whole operation, restructuring spreadsheet assumptions, I am then able to establish a value and analysis a customer can take to the bank. Or the bank can find comfort in. Or the lawyers can use to establish equity. The net result is a written report sometimes up 100 pages long. This one is. Having eyes to see behind the curtain is a marketable ability.
