Hey,
I saw you guys had mentioned us in an email thread about this.
We'd love to help with your crowdfunding project and are big fans of *nix and open source. Let me know if you have questions.
I can send pricelists for hats/tshirts/hoodies/postcards/posters to the appropriate contacts, and can get you guys a $25 voucher on stickers from our friends at StickerMule.
Thanks!
Nick, Founder
