William and Friends,

Could you tie-in one or two special bumperstickers with your flyer campaign? Perhaps the bumper stickers would go well on work trucks and construction vehicles?

They could have a slogan that encompasses in six or seven words what your flyer campaign is about. Or, perhaps they could say, "Proud to Hire LEGALS" with a hard hat and American flag logo. I could see construction vehicles and vans sporting such logos!
Or, "Proud to hire AMERICANS!"

Any sort of catchy merchandise that you can tie-in with the flyers may help the flyers to catch on more quickly. Just a thought.
