I’m trying to buy a book for someone who has a product that she is eventually going to turn into a brand. The book needs to be of the basics; How to copyright, produce, accounting, marketing, etc.

I have an idea for a household product, that I think would actually take off and people would buy. Any suggestions/ideas on where to begin?

I want to buy it but I do not know if it is worth the money. If you haven’t even heard of it please don’t respond.
