Basic E-Commerce Site Design

I’m looking for a clean, intuitive website design whose sole focus—at this stage—is an attractive product catalog. The goal is to give shoppers a comfortable browsing experience and present each item clearly, ready for when I add checkout functionality later on.

Key points
• Project type: Website design for an e-commerce store
• Must-have feature now: Product catalog (no cart or reviews yet)
• Devices: Desktop and mobile views
• Style: Modern, easy to navigate, fast-loading layouts

Deliverables
1. Wireframes covering home, category, and product-detail pages
2. High-fidelity mock-ups in Figma, Adobe XD, or Sketch, including responsive states
3. Basic style guide (colors, fonts, button states, spacing rules)
4. Handoff file ready for developers (assets sliced, fonts detailed, design specs annotated)

Please share relevant portfolio examples of catalog-centric e-commerce designs and your estimated timeline for this straightforward first phase.
