Shopify site

I'm looking for an experienced developer to help me create a Shopify e-commerce store. I have a specific theme and design in mind for the site and need help setting it up correctly with the right features. In particular, I want to make sure product reviews are integrated so that customers can leave feedback. It's essential that the site works properly when it's finished, so I'm looking for a talented individual who knows how to use Shopify to ensure the end product is professional and user-friendly. We are using Unleashed software for inventory management system. I need someone that can sync the two through API, also need to be able to handle multi level categories, and attributes. We also have need to have log in for our dealers B2B with customer contract pricing available. Need Art, Content, and product descriptions work. Social media integration, newsletter integration segregation (dealers, and consumers separate.). We want to sell retail, and we also want log in for wholesale customers, and be able campaign to these customers differently.
