How was the quality of their shirts and hats?You could start with vistaprint http://www.vistaprint.com/business-cards.aspx?xnav=LeftItem&xnid=BusinessIdentity&dng=1141706
They've got tons of options to get you started, different templates, colors etc.
I've used 'em for cards, folders, postcards and just recently t-shirts, hats and yard signs. Good stuff.

I'm not scared of the computer, been on 'em since i was 10good ... and ...bad....MY fault for the bad...new logo is VERY busy...doesn't work for small print area
vistaprint kicks ass...kicks ass
but, i'm somewhat adept at the 'puter, so that helps
