Unusual question for DUers regarding publishing house connections?

[OneGrassRoot]

I'm not inquiring about having a book published. I'm hoping there are DUers who are associated with established publishing houses who may peruse these forums. :)

I have an idea that's been brewing for a while, and the publishing arena has just recently entered my thoughts regarding this overall gameplan.

I haven't done extensive research as yet into whether or not something similar exists, but I'm sure you brilliant people will bring it to my attention if it does. I will be doing research this weekend.

I'm trying to find a likely list of "mainstream" publishers (i.e. those with $$) who have the means and resources to start a specialized imprint. This imprint would only publish books which are associated with raising awareness (and thus funds through book sales) for a variety of social/health/educational/environmental issues. It could be fiction or nonfiction, but the messages in the books would lend to a natural partnership to raise awareness through NGOs, etc.

In essence, this imprint would translate into a brand known for such publications. So, to clarify, I'm searching for a large, established publisher who may be open to boosting their image by branching out into an area not previously explored through a new imprint. It's always who you know, not what you know, thus my posting this request amongst those I respect tremendously: DUers.

I have many, many more specific ideas and plans, but hopefully this basic summary will connect me to anyone here who may be able to point me in the right direction. This is really the culmination of a project I started nine years ago, and I never saw it going in this direction previously. But it's a perfect vehicle.

Thanks in advance for any replies!
