Add Calculator Page & Brevo Integration to Existing HTML Landing Page (Urgent, 24hr Deadline)

I have a single-page HTML landing website and need to add a second page with a simple calculator displaying amounts based on a slider. The design for this new page is ready in Figma and needs to be converted to clean, responsive HTML.

What I need:

✅ Convert Figma to HTML for the new calculator page.
✅ Add a slider-based calculator displaying these amounts:

10 months – £333.33 pm

12 months – £83.33 pm

24 months – £45.54 pm

36 months – £31.77 pm

48 months – £24.91 pm

60 months – £20.82 pm

✅ There are two forms on the site:

Form 1: Triggers automation flow A.

Form 2: Triggers automation flow B.

You will need to integrate both forms with Brevo (formerly Sendinblue) to capture leads and trigger the correct automation workflows upon submission.

Requirements:

Strong experience converting Figma designs to HTML.

Experience with Brevo API for form capture and automation triggers.

Immediate availability to start and complete within 24 hours.

Ability to test and ensure the forms and automation flows work end-to-end.

What I will provide:

Live URL of the current landing page for context.

Figma link for the new page.

Text document summarising structure and copy.

Please fully review the live URL, Figma design, and Brevo integration requirements before bidding.
I will accept sealed bids only.
