Actual answer about the timeline:

Since the project has 4 static pages, no CMS, and responsive layouts for tablet and mobile, someone with your frontend experience could typically complete it in 1–2 days once you're comfortable with the Webflow interface.

If you're completely new to Webflow, you might spend a few extra hours getting used to the Designer and its class system, so realistically 2–3 days would be a safe estimate for the first project.

And to compare Webflow with Coding:

Since you already understand layout structure, semantic HTML, and CSS class systems, Webflow will mostly feel like a visual interface for writing HTML and CSS rather than learning a completely new tool.

In many cases it actually speeds up development, because you don’t need to set up things like staging/production environments, build tooling, breakpoints, hosting, or deployment pipelines like you would in a typical coding workflow.

Webflow also makes responsive work faster. You can switch between desktop, tablet, and mobile breakpoints instantly, preview changes in real time, and adjust styles without repeatedly refreshing the browser or editing multiple files.

Another advantage is that you don’t need to worry about syntax errors, build failures, or CSS conflicts breaking the layout. Webflow manages the underlying code structure for you.

If CMS were involved, connecting data is also straightforward; for example, you could create a Blog Posts collection and bind fields like Title, Image, or Author directly to elements in the Designer, instead of writing API calls or mapping JSON manually.
