Modular Marketplace Website with ERP

I need a full-stack partner to build a marketplace site inspired by https://tuzonamarket.com/. The platform must feel as fluid and robust as an ERP such as Odoo while staying modular, scalable, and secure.

Core requirements
• Product scope: the catalogue will host physical products only.
• Payments: integrate PayPal as the initial gateway, keeping the architecture open for future options such as credit cards or bank transfer.
• Advanced search: filtering by categories, price range filtering, and keyword search must work together seamlessly and return results in milliseconds.
• Order flow: shoppers complete checkout, trigger dispatch logistics, and receive real-time status updates; sellers view packing slips, labels, and tracking in one dashboard.
• Metrics & reporting: sales, inventory turnover, and traffic reports exportable to CSV/PDF; administrator dashboards with drill-down charts.
• ERP-style management: clear modules for products, customers, orders, accounting hooks, and user roles—each deployable or upgradable independently.
• Security & compliance: HTTPS, PCI-ready code paths, robust RBAC, and audit logs.

Technology is up to you, but I lean toward a modern stack (e.g., Django + React, Laravel + Vue, or Node + Next.js). The code should be clean, documented, and stored in Git; CI/CD to a staging server is expected.

Deliverables
1. Working web application deployed on my VPS.
2. Source code with installation guide.
3. Admin manual and user guide.
4. 30-day post-launch support for bug fixes.

Show me previous modular ecommerce builds or ERP integrations you have completed, outline your proposed tech stack, and provide a timeline with milestones for MVP, testing, and launch.
