i have found a great place for logos that you can download and resize to your appropriate scales. we use this at work all the time ( a sign company), and i forgot about it until tonight. hopefully this may help anyone who might want to use it

just click through to one of the companies and look for "samples" or "portfolio" in the header, I found tons of them, most were too modern for me, but some could be adapted.
