Build an Online Store

Need a complete Shopify Store Setup with pre-defined Theme and Customizing the Product page to handle Custom Stitching options... Some of the major functionalities: 1. Shopify Private app (like [login to view URL] ... do not copy their code or any proprietary information) 2. Inventory for different variants ( 1 product should be shown with multiple options i,e size, height). Payment will be made once we see a working site.
