I think you are missing the market research step. You need to ask the people that you would be targeting, because at the moment, I'm unsure why someone would use your product, over say using a platform where they can hire an online tutor and learn from them, or use Rosetta for example. I get that you have the learn about Latin Culture component, but are potential clients really falling over themselves to learn more more about this market, that they would pay for it, especially when google is so helpful.

Also, freelancers, entrepreneurs, business owners etc is a pretty large group, maybe start with narrowing that down, then asking them directly, if it would be something they want to buy, or you could also test the idea using something like Udemy.
