Professional Services Marketplace Platform

I want to launch an online marketplace that connects clients with professional-grade service providers—specifically legal, accounting, and similar advisory fields. The core experience is simple: clients post a detailed request, and registered professionals reply with tailored offers they can accept or negotiate. No browsing catalogues for now; the request-and-proposal flow must feel effortless on desktop and mobile alike. My priority is to release a functional MVP within a month, so the build needs to stay lean yet future-proof. You’ll architect the platform, design the key screens, and take it live on my hosting account. Deliverables • Responsive web app (or hybrid mobile) with separate client and professional dashboards and iOS and Android APPs • Post-a-request wizard, real-time offer inbox, basic chat and file exchange • Profile pages for professionals, capturing credentials, specialties, and star-rated client feedback • Admin panel to moderate users, view analytics, and manage disputes • Secure authentication, role-based permissions, and GDPR-compliant data handling Acceptance Criteria • A new client can publish a request and receive at least one live offer in under five minutes. • A professional can complete onboarding—including identity verification upload—in under ten minutes. • All critical flows pass cross-browser tests (Chrome, Firefox, Safari, Edge) and mobile breakpoints. • Deployed instance is performant (<2 s page load on a 3G connection) and fully documented. If you have proven experience building two-sided marketplaces, especially in regulated sectors such as law or finance, I’d love to review your approach and timeline. Further details in attached
