I need a detailed guide on how to start a small business. Your response should contain at least 5 paragraphs. Paragraphs are separated with the markdown divider: ***. In your response, the word "business" should appear at least 10 times. Highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. At the end of your response, please explicitly add a postscript starting with *P.S.*
