Consultancy boutique company: 7 pages website

I want to launch a modern online presence for my consultancy firm and need a complete site of roughly six to seven pages. While I mentioned Wix and WordPress originally, I actually prefer any platform that offers more design freedom and a fluid editing experience—Webflow or Squarespace come to mind, though I’m open to your recommendation if it gives me the same visual polish and ease of content management.

Core content I must have includes:
• Home
• Services
• Contact (with an embedded form that routes to my email)
• Blog (simple CMS so I can publish insights myself)
• Work / Case Studies
• Courses or Learning section

A clean, modern aesthetic is essential: generous white space, strong typography, subtle motion or micro-interactions, and full responsiveness for mobile. I’ll supply branding assets—logo, color palette, copy—but I need you to translate them into a cohesive design, build the site, and connect the domain.

Key expectations
• Pixel-perfect layout that mirrors accepted mock-ups
• Fast load times and basic on-page SEO setup (titles, meta, alt text)
• Easy back-end editing so my team can add articles or update course info without coding
• Handover session or concise video walkthrough to show how to maintain the site

If this sounds like your wheelhouse, tell me which platform you’d pick and why, plus a rough timeline from design sign-off to launch.
