You have a product, service, or potential sponsor and you have no idea what to charge. Some questions you may want to ask

1. How niche is your audience? (the more niche - the more you can charge)
2. What problem does your product solve?
3. Can you make money with your product/service?
4. How will you charge (avoid CPM for sponsors)
5. Whatever you first land on for a price it is probably not enough (we all underprice).
6. What is the cost of your product/service
