American Mahjong Source Code Needed

I am looking to purchase a complete, production-ready source code package for an American-rules Mahjong game that runs natively on Windows. The build must already include a working multiplayer mode—whether peer-to-peer, LAN, or server-based—as this capability is non-negotiable for my use case.

To keep onboarding painless, I need a clean, well-commented codebase plus any assets, libraries, and tools required to compile and ship a Windows executable. Please include brief setup instructions so I can compile the project on my end without guesswork.

Deliverables:
• Full, unrestricted source code and game assets
• Clear build/compile documentation for Windows
• Confirmation that multiplayer functionality is stable and ready for immediate use

If your existing project meets these points, let me know what it’s built with and how quickly you can transfer the files.
