We need about 50 icons for our Windows application. These icons will be used on user interface buttons and other elements. The icons will be 48 x 48 pixels and use 16 bit colors. We prefer Windows .ico format but .bmp will also work as long as you provide the same background color for all icons. If using .ico format, the background will be transparent.
I'm looking for professional 3D icons that are consistent with Windows guidelines. Please submit some samples if you've worked on icons before.
For a sample of some of Windows icons please look at the zip file provide here. In Windows, the easiest way to view them is to unzip this into a folder and view that folder in Thumbnail view (in Windows explorer select View->Thumbnails).
