Logo and Favicon Redesign

The actual Logo and Favicon of my Site [login to view URL] should be redesigned. The goal is to have a Logo and a Favicon that suite to each other. The Logo must be resizable to various sizes. The Logo should not have a Slogan below it. At least 3 different Logos and Favicons should be provided as a Draft, from which I will decide which should be the Logo you should provide a high resolution version. It would be great if even a 3D-Logo is possible in addition to the selected Logo. The Logo does not need to be as the actual one, but it should have the same or similar colors. You will be provided with a mockup of the new site design, when you win the project. You will need to deliver the Logo in various file formats, that it could be used on the Web as well as in Print Media.
