shopify help

some people at getting it wrong and make sure you read this very well ;Build responsive and professional Shopify dropshipping store for lingerie brand. My fiance and I are launching our own lingerie brand and need a website created. We already hired a logo and brand identity creator and have all the files needed such as logos and colors. We also have a USA based supplier who we will be using exclusively and want their products to be what we feature on our store. The supplier provides a CSV and XML of their products and also provides a CSV link for supply levels. I need these integrated into the website so that supply levels are always accurate. My fiance and I are both professional photographers and videographers so we will be creating many of our own photos and videos for the brand but for now, we can use the supplier's stock photos
