Checked out your twitter and facebook. Take my advice with a grain of salt.
You have a small following. That's not a bad thing, but that means you can't really rely on the social media blast strategy. You have to individually email, facebook message, and twitter DM/mention people in your following and specifically ask them to pledge or support you in a tangible way. I guarantee you you will get better results (ROI) for the time you put in.
These guys said it pretty well:
