Go to
www.logoserver.com and get already created logos there.
Check out logos for a lot of leagues in all kinds of sports.
Most will probably already have a city name and nickname.
There are also team symbols minus the city name.
See the thread "Eugene Church Logos"...you are welcome to download any logos there you like.
The creative guys are real good about helping you.
They will respond to your post when they have the time.
