Sleek 4-Step Onboarding Form

My WordPress site (Elementor-based) needs a premium, four-step onboarding flow whose sole purpose is to collect user information. I already have the field list and copy; what I’m missing is a modern, visually polished front-end that feels effortless on desktop, tablet, and mobile.

Here’s what I expect from you:
• Design and build the four sequential screens directly in Elementor (custom CSS/JS is fine where native widgets fall short).
• Add a clear progress indicator and smooth animated transitions so users always know where they are in the process.
• Handle inline validation and error messaging so incomplete fields never disrupt the experience.
• Ensure the final Submit event stores the data in WordPress (I’m open to using Elementor Forms, Gravity Forms, or a small custom endpoint—whichever you’re fastest with).
• Match the rest of my site’s typography and colour palette while keeping the overall look modern and sleek.
• Test responsiveness and cross-browser behaviour before hand-off.

I’ll provide staging access, brand guidelines, and any plug-ins you need. Once the flow is live and data is coming through cleanly, the job is done. This information also stores in hubspot and sends an email notification.
