WordPress Multi-Vendor Marketplace Developer

We are building ShopKori, a Bangladesh-focused e-commerce platform combining four business models in one system: 1. First-party (1P) store — our own sourced products 2. Multi-vendor marketplace (3P) — independent sellers list and sell their own products 3. Reseller program — entrepreneurs buy at wholesale rate and resell at their own markup 4. Dropshipping program — zero-investment partners take orders, we fulfill directly 5. Affiliate program — referral-based commission earners We have a complete, detailed requirements document (PDF) covering every module, user role, payment/escrow logic, courier integration, and a phased build roadmap. This will be shared with shortlisted candidates.
