Check the Small Business Administration. I do not know for sure that they have information specifically on starting a non-profit, but they have a ton of tools and resources to guide you in starting a business. I have been using this lately as I am trying to expand my own small business. There are also lots of resources on writing a business plan, grant and funding information and so on. If they do not address non profits directly, my guess would be that they may be able to point you in the right direction. They have online mini courses about business which, upon completion, you can print out a certificate for. My understanding is that when submitted with a business plan, any education or experience that you can demonstrate will help with getting support for your endeavor.

I have worked for a number of non profits, but have not started one. I would just suggest that you have a defined mission, and plan before anything else. From my own experience, especially with my hypomanic episodes, sitting down and focusing what I am trying to accomplish with my business was eye-opening. Of course, I get all sorts of fabulous ideas, and want to be all things to all people. I have learned that defining the purpose and structure of my business has helped rein me in a little bit.

I wish you the best of luck.
