Oh cool! Creating a digital product sounds awesome. I know what you mean, about not being a sales or marketing guru. One of my first ecommerce stores (it was a Yahoo store, if that tells you how long ago it was haha) failed because I didn't know sales or marketing. If you have the capital, it might be worth looking into outsourcing to a pro to handle it for you, unless you're learning it on your own. Lots to learn for free on YouTube, Tik Tok and other places online.
