Create New Icons

Hi, I am interested in creating 6 windows icons (24-bit with 8-bit alpha making it 32-bit). Each icon would contain three sizes, i.e. 48x48, 32x32 and 16x16 images. The icons will eventually be used for a software product. I will give specifics for each of the icons once we have selected someone for the project. Please show me of the best work you've done in this area. I am looking for something creative and unique, not just generic images.
