Ask HN: How do I acquire funding for a startup non-profit?

It seems that my killer idea is not a fancy new something that will make me millions. In fact, it's quite the opposite: a non-profit. It's unique enough that I am almost sure of its success, though again that doesn't mean my bank account will explode. I suspect even if all goes well I would take a serious hit to my income should I work on it full time.

That said, I do want to work on this full time.

I have never tried getting funding before. Does anyone have any experience or pointers specifically related to a startup non-profit?
