Getting a good design is the buyers job, as well as the designer's. Good art is not easy nor is it automatic. If you are new to composition and creativity admit it and with that awareness, you can find allies who can help, starting with the staff of 99designs. If you've created, made things you're happy with, then the design process will be fairly easy and straight forward. If not, then be ready for an enjoyable experience, as the staff at 99Designs and the amazing (and some not so amazing) Designers offer their ideas. Then you need to say what you think and want. That's the fun yet tricky part. Do you know what you want? Can you put it into words your Designers can use as feedback?
Welcome to Art and the world of graphic design. It's here, if you're ready and it works, it really works! You'll get out of it what you put in, teamed with your designer.
