Actually, I am currently haven't the same struggle with question #3. My partner and I started an LLC and then later developed a product. Do we start a new business for this product? If so, do we dissolve the first business? Should the LLC start a new business? Use a DBA for the product? There are so many questions that aren't easy to research because of their specificity. It would be great for some experienced business hackers to weigh in.
