Hello,
We can use a platform such as wordpress, opencart or prestashop to create an ecommerce website.
From my experience I recommend wordpress as it has a lot more support and free plugins.
Setting it up is a quick and easy job, populating it might take longer depending on the data that needs to go in and cost more.
Do you only want it setup, or you need it populated as well?
Kind regards,
Radu Dinca
