Hi Sokka, and thanks for your question. First of all, creating logos isn't easy and takes some creative talent to accomplish. I know you're doing it for a class, so if you need some help in that area, you can check out www.thelogocreater.com which is a nice piece of software to help.
Secondly, if we could see an image of the logo you've created, we might be able to help you with a snappy phrase. Either send us a link where you've uploaded it, or the "insert image" tag at the top (sixth icon from the right) to insert it in this post.
Mike
