Need Retina iOS app icons with excellent graphics

We have a very tiny application and need just the app icons. These icons include: 1. 114x114 icon for retina display 2. 57x57 icon for the standard display. 3. 58x58 icon for search. 4. 512x512 icon for the iTunes Art Work. Please contact only if you have sufficient experience developing iOS application icons. iCons must be have squared corners and mut not use flashy colors. In fact the colors must be subtle and textures must represent the nature of application. To give an example - Icon for iBooks has a wooden texture and a book that just tells the user that it is a library icon.
