Welcome to the party.
WooCommerce is a great place to start for someone in your shoes. It’s built on WP, which I know you are already very familiar with, and since you are selling info products it will have everything you need.
Now that you have made the jump to the world of eCommerce and shopping cart platforms, you will soon see that your options for making money are virtually unlimited. Once you build up your eCommerce knowledge, you can easily move into physical products, perhaps starting with offering your products on DVD and/or printed books, posters, etc. You may be surprised to discover how many of your customers are willing to pay extra for a physical printed hard copy of your info product.
It’s only a hop-and-a-skip from there to selling virtually all types of physical products via drop shipping or using a fulfillment service.
