Glad to offer my perspective! There's a ton of conversations on this kind of stuff out there on arts and crafts forums. That said, I found this book in particular very helpful. It covers all sorts of stuff, but it's not exhaustive, so you might need to look at other sources, such as the local branch of The Small Business Administration, your local library will probably have model business plans available, and your state department of commerce will probably have resources on top of that. There's a LOT of stuff out their for entrepreneurs, and fortunately, a lot of it is easy to find.
