I have a company logo and I've never created a banner. The banner will be going outdoors at a baseball field and will be 3 feet x 5 feet and will need to be readable from about 300 feet away. I'm not sure if my logo is readable from that far away in its current form. I'd like to try to keep the logo the same but add the phrase "IT Support For Charlotte & Lake Norman since 2002".
You can check out my web site at www.nucentric.com for some of the imagery that we use. I'm attaching a couple of files including our logo as well.
