Don Imus could be an avenue, he has his own charity ~ the Imus cattle ranch for kids with cancer ~ and his wife is active in several causes, he's probably too busy to get involved much, but I'll bet he'd would be willing to give airtime. I can't commit right now to trying to contact him, but will do so in the future, if no one else does so. Controversial or not, once he takes up a cause, he gets it public attention.
