Wordpress one page

I need a responsive landing page built on WordPress and fully editable with Elementor. The focus is on conversion for direct sales, so I highly value fast loading speed, mobile-desktop optimization, and a clean, professional, and corporate design that guides the user without distractions.

Desired Flow
The visitor arrives at the page, completes a detailed form (multiple fields, clear validations), and upon submission, is redirected to a link to schedule their appointment at Cal. Each form response should be instantly recorded in a Google Sheets spreadsheet for seamless data analysis.

Preferred Technology
WordPress + Elementor so I can later modify text, colors, and images myself. You can use plugins like WP Forms, Contact Form 7, or similar; the important thing is that the integration with Google Sheets is automatic and stable. Google PageSpeed ​​metrics must remain positive.

Key Deliverables
• A landing page ready to publish, with a professional design consistent with the brand.

• Detailed form connected to Google Sheets and redirect to the calendar page.

• Brief instructions (video or PDF) on how to edit the landing page in Elementor and how to access the collected data.

I consider the project complete when the page loads in under 3 seconds, the form submits data correctly, and the calendar link works on both desktop and mobile. I look forward to your proposal and estimated timeline.
