Rose here from Shopify. Thanks for reaching out!
Do you have an idea of what you would like to sell? If not, we have a great blog post on the top trending products of 2020 to give you some ideas. You can sell a product you've created yourself or you can look into dropshipping.
If you've never heard of dropshipping, we have a great guide on getting started with dropshipping on Shopify here. Ultimately, dropshipping allows you to sell products that are created, stored and shipped by a third party supplier. You do not have to pay upfront costs for inventory. This business strategy is cost effective and very popular amongst our merchants.
If you are interested in getting started with Shopify, you can follow our step-by-step guide. From here, you will find a link to begin your 14 free trial allowing you to familiarize yourself with our platform and start building your website.
I hope that helps! If you have any other questions, please let me know.
