Can you build a website on BigCommerce Platform

I am seeking someone that has knowledge building websites using the BigCommerce platform. I have an Amazon FBA account, a toy store Facebook Page with a shop page, a buy sell trade group that links to my facebook toy store page and a Pinterest account. I sell a lot through facebook marketplace platform also. I would like my BigCommerce toy store website to be linked to the facebook marketplace.

If you have built a Bigcommerce site before I would be interested in interviewing you to help me set one up.
