Re: A question about to be an LLC or Non Profit
I just completed a Master's Degree in Public Administration, which had a heavy dose of non-profit admin. Many programs like this exist and are often looking for real-world projects. Hit up the MPA program of your local university.
There is much more to creating and running a non-profit than getting the tax-free status. Start considering now who will be on the board, drawing up by-laws, etc.
There are a number of good books on Non-profit Management. Familiarize yourself with them, especially if you are going to run a foundation and a business. They have a lot in common, but some substantial differences you need to be ready for. Just like starting your business, the better prepared you are, the better the foundation will run. Good luck!
