Hi there, I can't really give you advice on where you can get your fliers designed but I just wanted to narrate an incident I saw.
I saw a guy outside a mall distributing fliers to people as they come and go. Most people take it and toss it without even looking. When I was coming back from the mall, this kid was still giving out fliers, this time they were all crumpled.
It was amazing to watch because people were opening up the fliers to see what was in it. Some still tossed it though - I though the kid was brilliant to think of something like that..
Anyways, just wanted to tell you that - good luck with your campaign.
