Professional HTML Order Confirmation

I need a clean, fully responsive HTML email that will serve as the order-confirmation message for my service-based business. The tone must stay strictly professional, matching the look of a modern SaaS brand—think balanced whitespace, clear hierarchy, and mobile-first design.

Inside the template I want three clearly defined content blocks:

• Order details – placeholder table for item, quantity, price, and total
• Service description – short paragraph area I can swap out per service
• Customer support information – contact email, phone, and a small FAQ link

Please code with inline CSS only (no external styles), keep the total width at 600 px for desktop, and use fallback web-safe fonts. The finished file should render consistently in Gmail, Outlook (desktop and web), Apple Mail, and leading mobile apps.

Deliverables:
1. One commented HTML file ready to paste into our ESP
2. Any image assets (logo or icons) referenced, optimised for retina displays

I will deliver logo, text and color palette for design purposes.
