Create Shopify Landing Page for a Product Offer

I am looking for a Shopify expert to help me create a landing page for a specific product offer with the goal of increasing sales. The ideal candidate should have experience in designing and developing Shopify pages and be able to work with my pre-designed layout in Photoshop. The landing page should be customized to match my brand and create a minimalist and modern look. I am looking for someone who can create a user-friendly interface that is optimized for a high conversion rate. If you have experience in A/B testing and conversion rate optimization, that would be a plus. Thanks for your interest! I need this completing by Tuesday evening latest.
