I need two shopify banner design for my store

I seek the creation of two visually compelling banner designs for an e-commerce storefront built on the Shopify platform. The banners should showcase products and services in an eye-catching manner to attract and engage customers browsing the site. One banner should promote newly launched items for the summer season while the other highlights top selling offerings. Both must incorporate the business' core brand colors and style guide elements for consistency across online branding efforts. Prefer candid product photography paired with impactful headlines and calls to action. Designs need to be optimized for responsive display on desktop and mobile devices alike. Candidates should have proven experience designing banners for Shopify stores or other e-commerce venues. A portfolio highlighting relevant projects along with the ability to concept, create and deliver high resolution graphic files within one week of receiving all source materials would be ideal. Please provide estimates based on the scope of work outlined. Compensation will be commensurate with design quality, on-time delivery and adherence to brief.
