Hi,
I see that you need a store designed in BigCommerce and I would love to be the one that helps you reach your goal. I have great experience with BigCommerce and have just completed a BigCommerce project for a client on here who owns a clothing store.
Since it is build on BigCommerce, you will be able to create new products and edit products as requested. Their backend is very user-friendly. We can add some great things to your site to really make it unique and successful. For my day job, I work as the internet marketing manager at a national retail company in the U.S., so I am greatly experienced with web design, as well as marketing, social media, email marketing, and other things. I look forward to working with you on this project. Please message me with any questions you may have. Thanks!
