Silly money isn't a good recruiting tactic in my experience (from the original dot com boom days - which was the only time I ever had silly money available :-):
* It motivates B and C players more. So you get a lot more chaff to filter out in your application process. You also get many more D players (the ones who are knowingly incompetent and are actively trying to deceive you into recruiting them).
* The major motivation of A players usually isn't money (once you reach the "fair wage" stage). So you don't attract that many extra A players.
* Some of the A players who do get tempted by the extra cash discover that it's not quite as wonderful as they expect and leave for more interesting work. Wasting large chunks of your time and money.
* It may turn some A players off. There's a unwritten rule that you get more cash to make up for dull work. So offering silly money implies to some that the work is going to be exceptionally uninteresting.
The absolute best way I know to recruit A players is:
0) Understand the role that needs filling and the kind of person that needs to fill it
1) Have a really interesting job
2) Know how to access the A players
(I'm amazed at the number of organisations I come across that skip step 0...)
