Who wants what I make How much will they pay for it
This is basically you asking your friends if they are willing to pay X amount for what you make. Then go to someone you do not know and offer it to them for that price and see what kind of reaction you get. You can also go to Survey Monkey and create a quick survey for your friends online to answer whether they would pay a certain amount for a certain kind of product or service. This will help with your pricing model.
