WordPress Developer — Content Site + Custom Interactive Calculators (7 tools)

I'm looking for a WordPress developer to build a content + interactive-tools site — three content pillars plus seven custom calculators that are the real centrepiece of the build. Full technical brief attached, covering brand system (colours/type, final — no design work needed), site structure, all seven calculator specs with formulas, and explicit scope boundaries. Quick summary of what's involved: WordPress + Elementor build: homepage, three pillar hub pages, blog, about, guides page Easy Digital Downloads set up for a small digital guide catalogue (4 products at launch) Mailchimp API integration for email capture, triggered from each calculator's export action Seven custom JS/React calculators built on one reusable input → calculate → export component (formulas provided in the brief — no research needed on your end) Mobile-first, SEO fundamentals, client-side PDF export on calculator results Full spec is in the attached document — please read it before quoting, as most scoping questions are already answered there (formulas, reference data status, explicit out-of-scope items, cost-control notes). Proposed milestones (open to discussion, but please structure your quote this way so proposals are easy to compare): Content site build Core calculator component (input/calculation/export/email-gate pattern) All seven calculators built on the component Final integration, testing, and handover Skills required: WordPress, Elementor, JavaScript/React, PHP, REST API integration, Easy Digital Downloads, Mailchimp API, responsive/mobile-first development Timeline: Flexible — please indicate your estimated turnaround in your proposal.
