When you create an MVP you shouldn't be thinking about the products success in terms of it's sales. An MVP is basically an experiment, you should be looking at feedback you're getting from it and how that feedback can be used to improve the product.
Do people like the product's goal but not a certain aspect of it? Great! Now go change that aspect and see what they think now. Repeat and repeat until the product is financial success.
If you're not getting sales that's fine, focus on just getting people more people to try a free account. Maybe change the homepage around one day, see how that affects the rate of sign ups. Keep experimenting and improving.
