Quick ways to create a product?

Hello,
I want to sell a product on a forum, but I don’t know how I can create a product fast. I also don’t know if I want to sell a physical or a digital product, but I think selling a digital product has more advantages.
So, a digital product, such as an e-book or small report, maybe?
How can I create a digital product fast? If somebody has some ideas I would love to here.
