I'm building a lead generation assessment tool for my existing recruitment website. Respondents answer 15 questions across 5 dimensions , see their results visualised as bell curve charts, then hit a gate form before accessing their full report. Pages and Bell curve logic is already designed. What I need built: Multi-step question flow (15 questions, 5 sections, progress indicator) Scoring logic (I'll provide the formula) calculated client-side Six bell curve visualisations displayed after completion, before the gate Gate form capturing: first name, last name, email, phone, LinkedIn URL On submission: POST all scores + contact details as JSON to a Make.com webhook (I provide the URL) Simple thank-you/confirmation page post-submit Responsive, works on desktop and mobile Not in scope: report generation, email delivery, CRM integration — all handled separately via existing automation. Stack: Your choice — keep it clean and handover-friendly. Vanilla JS or lightweight framework preferred. Must integrate with an existing WordPress site. Deliverables: Working build, webhook tested, commented code, brief doc covering how to update questions and webhook URL. Timeline: 2 weeks preferred. Please include examples of similar form/assessment builds with your bid.
