Vision-Inspired Shopify Store Development

I need a Shopify shop set up for my dog product. It’s a Calming Oil to help with bad behaviour. It’s called CHILL DOG CALMING OIL. My brand will be CHILL DOG. At a later stage I will add more branded products. I have a brand identity & product images. I need help making my Shopify shop look professional & a better understanding of how it works
