I need a fully custom-coded website for our private medical center, delivered within three weeks. Off-the-shelf CMS solutions such as WordPress are out of scope—I’m after a purpose-built application that is secure, fast, and easy for my staff to manage. Core requirements • Appointment booking: I’m flexible on the exact solution—build it from scratch or integrate a reputable third-party service if that speeds things up. What matters is a smooth, mobile-friendly patient flow from slot selection to confirmation. • Payments: the site must accept Credit/Debit Cards and PayPal through an industry-standard gateway, with tokenization and clear error handling. • Invoicing: every completed booking should trigger automated invoicing, and I want the ability to design customized templates that reflect our branding and let staff add notes when needed. Please use a modern tech stack you are comfortable supporting long-term (for example React/Vue with Node/Laravel, or a comparable combination). Clean, well-commented code should be stored in a git repo that you will hand over at project close. Deliverables 1. Responsive front-end with branded UI/UX 2. Secure booking module connected to our chosen calendar system 3. Payment processing flow for cards and PayPal, fully tested in sandbox and live modes 4. Invoicing engine with automation and editable templates 5. Administrator dashboard for appointments, payments, and invoice exports 6. Deployment guide and two weeks of post-launch bug fixing If this timeline and scope fit your expertise, show me relevant medical or booking projects you’ve completed and outline the tech stack you propose. I’ll move quickly on the right match so we can hit the three-week deadline.
