Plese help me to figure out these questions below, thank you

1. Apply product, price and place to your idea, being careful to identify at least one product success factor.
2. For the 'promotion' factor, explain what is required to obtain free publicity. Create one promotion concept for your idea that you believe would generate free publicity.[This part, and the next question on social media, are also often done poorly in the business plans. Think of something specific and original here. "I'll get a celebrity to post a picture of them with my product on Instagram" is not free (or creative)]
3. For your idea, what will be the key assumptions you will make in terms of sales price and volume. What EVIDENCEcan you use to justify these assumptions?
4. For your idea, how will you utilise social media?
5. For your idea, who will be your sales force, how will they operate and how will they be incentivised?
