Just wanted to let everyone know about iStock, which sells high-quality royalty-free illustrations (plus photos, video, and audio) for not much money. Do a search for "beer label" and you'll see many designs that you could simply add type to. There are also great illustrations you can use on their own. Here are some I'm working on (I'm using the watermarked images until I decide on one the file I purchase will be high-resolution without the watermark).
Send me a message and I'll hook you up with 10 free credits.
