Shopify theme changes

I am looking for a skilled Shopify expert to make changes to my online store's theme. The changes required include both layout/design and functionality/features. I will provide branding information later, but the ideal candidate should have experience in incorporating branding elements into Shopify themes. Additionally, the project must be completed in less than a week, so the ideal candidate should be able to work efficiently within a tight timeline. Overall, I am looking for someone who is detail-oriented, communicative, and capable of delivering high-quality work.
