I don't know if this will be "pointing you in the right direction" as you said. But I vaguely remember on one of my web designer friends doing this for someone about 5-6 years ago. This person contracted my friend to do a corporate logo background that would be used on approx 50-60 machines.
I don't know what he did "step by step" but I do remember him saying that he utilized the services of Adobe Photoshop, I think he said he scanned the persons company logo, which was on paper into his computer, fired up Photoshop and opened the file in there. Then he said something about having Photoshop trace or mirroring the image, I don't know, I'm not real good at this Photoshop stuff, But I do remember him using the terms "trace" and "mirror" and "scan"!
So to me, it sounds like if you have your corporate logo on paper, you might have to use something to get it into your machine.
I'm sure there are some photo and image savvy members here on TechSpot who are more superior than I when it comes to creating images, I hope one of those kind of people chime in here to try and help you out, for I'm drawing a blank!
Good luck.................
