Letter Topic

I have been having a pretty hard time coming up with a topic or someone to write to but I think I'm finally getting somewhere.
Something that has always been important to me has been making a difference even if in the smallest way possible, because it's still a difference.  There are many people I can write to in this category but one in particular could be someone who works for the organization, "do something." "Do Something" is an organization that helps kids who make a difference in their community.  The organization gives away grants and scholarships to these kids.  The kids come up with these ideas on their own and help so many different people in need and not just people but animals as well.  The organization also has an awards show called "The Do Something Awards" when celebrities win awards for doing charitable things and helping out; but they also pick 5 kid finalists and choose a winner for the "best cause" and give I think 10 million dollars to that cause.
For my letter I was thinking of writing a letter to the editor saying that I really love the idea of this organization and talking about how more kids should be involved with this program and talk about bringing awareness to this organization.  I can also maybe think of a cause and talk about what I would and could do to help.
As of now that's all I can think of but I think I'm finally starting to get somewhere!
