I'm sure you've already thought about it, but your stories would be PERFECT for Oprah's show. Due to the NBA playoffs, DateLine is going to show pretty early or pretty late in some areas and that means that many will miss it who might otherwise have been in a position to see it.
Have you thought about contacting the Oprah show about your stories and the issues involved? The topic is perfect for her format and you will have lots more time to discuss the subject than DateLine is able to allow.
