How do you go about creating such a program? If you don't have any original material, then find some well-respected people in aviation and ask them for their best bit of advice on the topic that you want to present. For instance, if your program is on preventing runway incursions, ask others with experience how they keep from stumbling onto a runway. Many experienced pilots enjoy sharing their wisdom. Ask for permission to quote them. Now, with quotes in hand, create a program based on this advice. For the program to be a success, you probably wouldn't need to do much more than present and discuss each tip.
What do you get in return? Exposure. Pilots get to know you and you get to know them. Because you've handed out your business cards and mentioned your Web address, it won't be long before you have people calling you for training.
