Yep. Easy way to find vectors if the client has no clue: google the name of the company/school/whatever + ".pdf" - zoom in on the PDFs to see if logo pixilates, if not, download the PDF and open in AI (or I guess Corel, whatever floats your boat) and strip the logo out of there. You wont get spot colors/pantones but like 75% of the time you can find a company year end report or letterhead that has vector graphics.
