If you want to provide information for a premium, using online tools, I suggest you use a freemium model.
This means offering information:
- For free, until you establish yourself as a a brand: Publish things so good / long / impressive, they can’t ignore you & you become a brand with that content.
- Ask for money, once you are a brand: Now you can sell other things:
The solution? Offer free until you become a brand & then charge for premium.
