I'm currently building up a NPO with my sister. It is tough work but far from impossible. We're using the book from NOLO called starting & building a non profit. it has templates and an interactive online version which makes things easier. Also there's Ashlee Launches - n youtube- she's got a few walk through's that I thought were helpful.
This is a perfect niche, I haven't talked to many graphic designers who do this! What an awesome idea. :)
Keep steeming! there seems to be a big humanitarian population here on Steemit so perhaps people on here may help fund your NPO.
