Need A High End Boutique Style Website On Shopify

Hello I am starting a new company on Shopify. I will be reselling high end miniature puppies for 5k each or more. I need a website to get started and I’ll probably need help here and there along the way as I get product (puppies). I can’t get puppies to list yet until I have my website ready to launch so there for there is no products to list yet. Once my webpage is ready I can get puppies from the breeders to list. I want to integrate a online chat as well. Also a way to take emails for people to sign up for newsletters and etc. I’m gonna need a client review page, faq page etc -
