Knight Online Multi-Account Management Tool ( cleintless no cleient login.)

Clientless ( no cleient ) Knight Online Multi-Account Automation / Management Tool
I am looking for an experienced developer to build a desktop-based automation and account management tool for Knight Online.

Project Objective

The main goal is to create a tool that allows multiple Knight Online characters/accounts to be managed from a single PC without requiring a separate game client window for every character, using only technically and legally permitted communication or integration methods.

The system should be designed to efficiently manage multiple characters/accounts from one computer.

Main Requirements

The tool should include the following functionality:

Ability to manage multiple Knight Online accounts/characters from a single PC.
A user-friendly interface for adding, removing, and managing accounts.
Ability to manage multiple characters simultaneously.
Account/character status monitoring.
Connection and disconnection status monitoring.
Automatic reconnection where technically possible and permitted.
Ability to send predefined messages to other players.
Ability to configure custom messages through the application interface.
Ability to select which character/account should send a specific message.
Message scheduling and configurable intervals.
Logging system showing account activity, connection status, errors, and actions performed.
Stable operation when managing multiple accounts simultaneously.
Low CPU/RAM usage is preferred.
The application should be easy to configure and operate.
Important Technical Requirement

The developer should investigate the available and permitted communication/integration methods for Knight Online and determine the most reliable architecture for managing multiple accounts without running a full game client for every account.

I am not looking for a simple macro or keyboard/mouse automation tool. I am looking for a properly engineered application capable of communicating with and managing multiple accounts efficiently.

Security / Verification

If the game uses CAPTCHA, authentication challenges, anti-bot systems, or other security mechanisms, the application must handle them through legitimate and permitted mechanisms rather than bypassing or defeating security protections.

The developer should clearly explain what is technically possible before development begins.

Deliverables
Fully functional desktop application.
Source code.
Build/compiled version of the application.
Configuration/interface for managing multiple accounts.
Messaging functionality.
Activity and error logging.
Basic documentation explaining installation, configuration, and usage.
Testing with multiple accounts simultaneously.
Developer Requirements

I am looking for a developer with experience in:

Network programming
Client/server architecture
Desktop application development
Multi-account systems
Protocol analysis where legally permitted
Automation systems
C#, C++, Python, or another suitable programming language

Please explain:

How you would approach this project.
What technologies you would use.
How many simultaneous accounts you expect the application to support.
Whether running multiple accounts without separate game clients is technically feasible.
Your estimated development time.
Your estimated total cost.
Examples of similar projects you have developed.

Before starting the full project, I would prefer to have a small proof-of-concept demonstrating the proposed architecture and confirming that the approach is technically viable.
