Marketing locally you have many options. Some that come to mind:
Are you using the university newspaper? It goes to alumni too.
Do you have business cards that look professional. Check out the "free" business cards at vistaprint.com. Then leave them everywhere!
Visit local stores without a web presence and do a quick mock-up first page for a site for them.
Go to local coffee shops with your friend (change locations frequently) and be heard talking about your business.
Design your logo and order logo clothing from a place like CafePress.com (very reasonable)
Check out local business expos / shows you can attend.
Leave flyers / business cards at local businesses. And go back again...and again. I would leave about a week to ten days between visits.
The more people you contact, the more sales you'll make. Good Luck!
