Wanna have Taylor Hicks at your wedding?

What about Daughtry band at your Bar Mitzvah?

For the right price, American Idol castoffs, finalists and past champions will pay a visit to the personal occasion of your choice.

"The average going rate for an American Idol finalist can be as little as $15,000 or as much as $150,000," a source familiar with the business of brokering singers, bands and other talent for corporate functions and exclusive private parties told The New York Post.

"But it really depends on what you want them to do. Are they just going to show up at the party or are they going to sing? Do they have a song on the charts right now, or are they yesterday's news?"

A wealthy entertainment mogul once shelled out big bucks - more than $30,000 - to hire second-season champ Ruben Studdard to sing just three songs at a party for his wife.

For gigs booked by less well-connected individuals, Studdard reportedly rakes in around $75,000 or more.

Hicks, the latest winner, fetches as much as $150,000 for a private performance. He'll be able to demand more if he ever becomes as popular as the original American Idol, Kelly Clarkson, who sources say is paid as much as $300,000 to put on a private mini-concert.

Carrie Underwood, who won the Fox TV talent show last year, commands approximately $250,000 to show up at a party and sing.

On the lower end of the American Idol pay scale are acts such as second-season finalist Kimberly Caldwell, who garners around $2,000 a gig. She received $7,500 in the past for an autograph session, however.

Not bad for a few hours of work.
