I want to create branded blank thank you notes and business cards to hand out to Wikimania Hackathon participants at the help desk at the Hackathon in Esino Lario.

The business cards will have the media wiki logo and a blank line for name / contact info on the front and a place for notes, etc on the back. People can fill them out and hand them out to eachother.

The blank Thank You Notes will have a mediawiki logo and a place to write "to ____" and "from ____" and a place to write a note.
These can be handed out to participants who want to give a quick hand written thank you to someone at the event.
