Have you done market research? The most important question will be: "How much individual blogger (in average) would pay for the premium product" If you want to learn from other peoples experience and mistakes (which is always a good idea) good questions are "Who are my core competitors and what is their business model", "Who have done something similar in other sectors (by other sector I mean for example news reporting in other media) and what was their business model and profit margin (and why you are different or similar)" and "Who have tried the same thing and failed and why they failed"? That's just some food for thought :-D
