Would there be a specific format to these tutorials? Are you targeting total financial incompetence, expertise, or both? The key thing here is to be unique in how it's presented. Especially if you're focusing on those who are relatively new to finance you don't want a stale, run-of-the-mill type of format. You want to apply an engaging technique (i.e. "The Midas of Numbers - Turning Your Knowledge of Finance Into Gold!").
Then you can build a couple of different e-books under that brand and promote them with affiliate programs like Clickbank. We have a number of e-book authors who apply CPA offers to help monetize their product on a "freemium" format. Tons of options out there for you.
