Platform selection

Hi all!
I am going to create a website for selling pyrography art where people will choose from a variety of options (wooden pictures, leather, etc.) where customers will choose type and size and then choose any photo or picture. After creating the pyrography by hand in high-quality and detail it will be shipped to their location.
I am not axperienced in website design so i would like to choose an ecommerce platform.
After a quick search i think that Bigcommerce is a good choice.
Do you...
