Ask HN: Where do I get an Android app icon?

My app desperately needs a new icon but I'm having some trouble finding a good designer. Where should I look for one? Ideally the icon would be in vector format.

I've already asked some random designers I've found on dribbble, but their price suggestions have been rather unrealistic. How much should I expect to pay?

I've also tried 99designs and that was a total disaster.
