I know I'm new, but I'd make a donation to the 'keep this game away from even semi-big name publishers' fund. Just my 2 cents.
If you appeal to the right communities and really get the name and stuff out there, you might be able to generate enough interest in pre-orders. For example, the Yogscast just ran an X-COM special over the holiday season (like the 27th of December or something?). Lewis claimed XCOM was one of his favorite games. Never know, the crew has a million subscribers... if he ran a livestream showing this game off, I bet it would generate interest.
Just an idea, but all things considered, I'll give you more money to stay away from a publisher.
