You can get one several ways. There are a few folks and vendors on here who can do it for you, there is Brew Brand Creative (name?), you can even ask graphic designers in your area to do it for you. There are ALOT of different types of software you can use to put one together as well. Most take a while to learn though (Gimp, Photoshop, Illustrator)... If you find an inexperienced designer who doesn't know what to charge you you can get away with paying only $45 or something or even a trade with your beer. But if you want something good that looks great and you'll be satisfied with it it can go up to a few hundred bucks.
