Shopify store expert

I'm looking for an experienced Shopify store expert to help set up and customize my store. I have specific design elements in mind, but open to suggestions. Although I do not have a specific deadline, I would like the project to be completed as soon as possible. The tasks I need assistance with include store setup and customization, product listing and optimization, as well as marketing and advertising. I'm looking for someone who has the experience and expertise needed to take my Shopify store to the next level.
