How can I sell my idea for an iPhone app?

I have what I think is a really good idea for a new iPhone app and would like to know if I can sell the idea.
I don't have any money to invest in development so I just need to sell the idea in it's raw form, I can write it up as I have experience of this but I just can't develop it myself.
So, who can I sell it to?
