Ready-Made .NET Core Travel System

I am a developer, but at the moment I’m no longer able to code. I am looking to buy a complete, production-ready travel agency system written in .NET Core. The package must already support online booking, integrated customer management, and a working payment-gateway module. Role-based access for Customer, Agent, and Admin is mandatory, and the interface needs built-in multi-language capabilities so new languages can be added without re-coding core features.


I will require full source code, database schema, and any build or deployment scripts so I can install the solution on my own servers and extend it later. Documentation should cover initial setup, configuration of payment providers, and the points in the code where branding or workflow customisation can be made.

Please provide a short demo or video walkthrough, mention the .NET Core version you used, and confirm that all third-party packages included are properly licensed for resale or commercial use.
I hope you can cooperate with me at a reasonable price within my budget.
