I need a favicon from the actual logo.

The favicon is the icon web browsers show up on the title bar or pages tabs. I have the original logo, but need the 16x16, 32x32, 48x48 and 64x64 pixels size icons (all on the same file). I should be two colors: white and the same green color used. No transparency. You can use IconWorkShop free software for this. [login to view URL] Maybe you already know it but if not, I think you will like it. The icons of course can not have the full details from the logo. You can delete the text, you can simplify the icon but should be tha same idea. If possible I want a green tiny border. Let's see wath you can do with the 64x64 first and when it gets OK just get it cloned to the smaller sizes. This will be easy.
