I need a single-screen landing page styled in a clean, professional and corporate look that mirrors the straightforward feel of the example at https://rubric.law/legal-resources/business-valuation-calculator/. The heart of the page will be a lightweight company-valuation tool. Here is what has to happen on that page: • Users enter basic financial data—at minimum revenue, expenses, owners salary, balance sheet value sector, depreciation and amortisation. • An automated calculation instantly produces a valuation figure. I will provide the simple formula; you handle the front-end and any necessary back-end logic. • When the result is shown, the visitor can click once to download a branded PDF report that summarises their inputs and the calculated valuation or receive and email with the valuation report. • Before the report is released, the user completes a brief form that captures: name, email address, phone number, company name, website, and whether they plan to buy or sell a business in the next 12 months. All collected data must land in a CSV or feed directly into my CRM via webhook—whichever you find faster to implement. Acceptance criteria – Page matches agreed Figma mock-up, loads quickly, and is fully responsive on desktop and mobile. – Valuation outputs the correct figure within ±1% tolerance when tested with sample data. – PDF carries my logo, colours, and a time-stamp, and is delivered automatically after the form is completed. – All lead fields populate in the CRM test record. – You hand over source files plus a brief setup/hand-off note so my team can host it on our existing WordPress / domain install (vanilla PHP or a lightweight plugin is fine). If you have a preferred stack for rapid, secure form handling (React, Vue, or straight PHP/JS), tell me up front—speed and reliability matter more than the underlying language.
