I saw a book in borders once, written by some guy who decided one day he wanted to be a CEO. But, like you, he didn't know what he had to be/do to become one, so he wrote to the CEOs of a heap of companies.
A few years later, he compiled the letters into book and now it sells for $17.95 or something.
Smart little bugger.
Anyway, my point is, why not find out some of the names of some CFOs and do the same? Write to them -- sure, some might be too busy: they'll put your letter in the bin. But there'll be others who might be flattered or like your initiative and respond. Everyone loves talking about themselves and giving advice.
Hey, at worst you lose a few dollars in postage.
