Classic Elegant Mobile App Logo

I’m looking for a designer who can craft a timeless, classic-and-elegant logo for my new mobile application. The mark should feel refined rather than trendy, scale cleanly from an app-store icon to larger promotional materials, and work just as well in full colour as it does in monochrome...
