There are actually two fairly good program to help with things like this... First, InFeRn0's 'Font Matcher' program will help you find if any fonts on you computer are at least close and could be modified/used directly. You get a bitmap image of a letter (or multiple letters, though it only does one at a time) and load it into the program, and the it will search through either all the fonts in your system directory or in a specific directory (like on a CD) and come back with the ones above a certain % match threshold you specify. The link to the page on it is
http://www.terra.es/personal/infern0/, but the page appears to be down at the moment, and when I tried downloading it a few days ago the full download did't work, and I had to find it over P2P.
If you're going to want to do lots of typing (i.e., not just create a few letters in Photoshop or the likes for one logo), you might want to consider getting High Logic's Font Creator program,
http://www.high-logic.com/fcp.html. I haven't had a chance to play with it, but it looks like it shouldn't be -too- hard to use to edit a font to be what you want it to be.
And no, I don't work for or have any affiliation with either of the above companies/people- 8) I just happened to have needed tools such as these myself a short while ago to match some fonts for a vid I'm working on...
