Replying to NEED SOME IDEA-Summer research sponsorship

so i'm filming a documentary out in Montana to advocate for the protection of the Scotchman peaks, an amazing piece of land that is currently unprotected.
I was trying to think of some outdoor company's/organizations that i could try to get some funding/spuuort from such as EMS, CliffBar, National Geographic

What other company's can you guys think of that might be interested in helping?
any ideas would be great, thanks!
