how much ayu was paid for all her performances?

[Manross]

Ayu is a popular superstar and most probably its not easy to invite her to any programs unless ure willing to pay a big sum i think...lets say, how much do u think ayu is paid for her performances in hey!x3, cdtv, music station and so on...
since those r all in japan, then if u wish to invite ayu to overseas to perform, u will have to pay a really HUGE SUM...e.g 2002 MTV Asia Award 2002...i duno how much she was paid for all her performances, but may be u ppl can suggest some figures?
