I make vinyl graphics as a side hobby and I have chatted with Steve about making up the logos as stickers for all of you. I made a prototype at my friend's graphics shop and I will post the pic here that I took after work tonight. I stuck it on at 1am so it was hard to make sure it was straight and hard to take a picture in the dark of night, but here's what it looks like...
I can make the one you see (16.5"x3") for $3.50 each and I can make the tall ones (bus on top and lettering under) for $10 each (they are 10"x25").
This is a 5 year vinyl and should hold up pretty good in all weather conditions. Even Alaska!
I am not making any money on these, the money goes entirely to my friend's shop to pay for the vinyl and I will even pay the postage. It's the least I can do for all of of the help you gladly give. My friend's website is http://www.mikespaintonline.com/
Visit it and take a look at some of his work.
