Shopify Website edit

I am looking for a Shopify website editor to help me make changes to my website. The changes I need are both in terms of design/layout and functionality/features. The product pages are my highest priority for edits and I am looking for someone who can add custom features to them. I don't have any specific design preferences, but I want the product pages to be image-focused and have a minimalist look. Ideally, the freelancer should have experience with Shopify website editing and be able to add custom features to product pages.
