How much money do you need for One Direction to come to your party?

I want One Direction to come to my house for my sister's party because we love One Direction. May some one please be kind enough to help me out here. I've been looking for hours!

you will need quite a few thousand dollars and you will have to book a few years before hand.
Ellen DeGenarous waited 2 years for them to get on her show :/
good-luck

I love 1D every girl wants them to one to there party, but you would have to book wayyyy in advance and have like a million dollars. But at the 1D Store they're selling life size stand ups. Buy each of them and ta da!!!!!!!!!!
