PETA, ASPCA and everyone else has similar pages. And that is the level or communication and transparency that leads to a growing membership.
But for an example y'all might be a little more pleased with, here's a PDF of the Ducks Unlimited fact sheet, which I think is very straightforward and easy to digest:

The biggest hurdle is not getting those things made, it is getting the numbers. Once you have the numbers and statistics and testimonials, putting up a web page or even making a flier is easy. And if that is what DU does, that is what the TDHA needs to do to reach that population of dog hunters.
