In US dollars how much did that paparazzi net for the topless photos of Kate Middleton?

It would be thought that the vacation home that the Royals were at was suppose to very secluded and in a secret location (too bad they did not have the CIA) so getting those had (or should have been) quite difficult to get. Having got what virtually no other photographer had and many magazines wanted, he could name his price. What price did you figure he let them go for in US dollars?
