no offense, but no one will want to carry around your CDs or resume. You can keep a few in your backpack, but don’t offer unless asked. A clever business card is always a good thing to have. Have your site on it, have music/sound design demos on your site. Make it easy to find. Don’t expect to find work, expect to make friends. Expect to learn and find others to earn with. Being a CA is a great experience, especially for your first time. Dress is pretty casual…I regularly conduct business in jeans/shorts/tshirts (and usually they’re clean!)
