Hello Patrick,
Unfortunately, the Community Tool Box does not print posters. However, we can give you some helpful guidance to hopefully meet your goal of obtaining traffic calming measures before there are excessive deaths.
First, you might explore Chapter 33 - Conducting a Direct Action Campaign to see if there are any strategies you have not yet tried. Chapters 30 through 35 and Toolkit #10 have additional information about effective advocacy as well.
If money is the only issue holding them back, then you might find out if there is a way to raise the money, perhaps by fundraising or writing a grant. Chapter 42 and Toolkit #14 have guidance for applying for grants.
Sincerely,
The Community Tool Box Advisor
