App icon design (logo)

Hi, I am looking for a graphic designer to create a logo to be used for a new iphone app I'm still coding. I need someone with experience and creativity and knowledge of iPhone app icon design best practices Image requirements: - should give an idea of photos moving to the internet, eg.a whirl of photographs below a cloud - original, flattened 512x512 png (do not upscale), 90° corners - flat or gradient background - prefer 1-2 color themes, maybe 3 but not more - bit depth must be RGB/A 32bpp - should not have any shine or gloss - do not use alpha transparency - should look good even downsized to 57x57 - icon should be presented in a clear and simple manner For the same image icon please provide a 256x256 round button on a transparent background (PNG format). Please look at other iPhone application logos to get an idea of what I need.
