Create several variations of music player for iphone app

I have created a music player as part of an iphone app. I need someone to create the custom graphics that I will use for the music player. I would like at a minimum 5 variations and up to 10 variations for the player. The idea is that the user will be able to select from the different variations how they want their player to look. Example themes for variations - White/classical, dark/grunge, girly/teen, retro/70's, etc... the themes aren't specific, I just need several different ones. Think of different music genres when creating the themes. Basic layout: Header and footer areas Buttons: Home List Play Pause Stop Skip Fwd Skip Bckwd Volume Fast Fwd Fast Bckwd Slider: Needs a top track, bottom track, and thumbnail slider image Background One 320x480 and 640x960 background image per theme No words on buttons or labels, all visual Each button will need a "unpressed" image and "pressed image". The actual "layout" of the page can be different or same but all functions need to be included. All images need to include 1x and 2x size (Example 60x60 and 120x120) In your bid please include the number of variations you will include and total price. I will consider the best price per # of variations.
