Promoting Charities

I would like to be able to promote lots of charities with this. Obviously the standards are there that Joss and company have supported, like Equality Now and Kids Need To Read. I can whole heartedly stand behind those. I would love to be able to promote for the Primary Children's Hospital and The Make A Wish Foundation. I'm open to suggestions on this too.

Does anyone have any ideas on how to do this? We're not going to be bringing in a bunch of money that we can donate, but there has to be a way that we can help out.

I've considered doing screenings where we could have the Utah Food Bank accept donations, but that's about all I have.
