VB.NET Apps Windows Service Development

I need a skilled programmer to create a Windows Service for my VB.NET applications. The service should enable a 'floating network' licensing option, supporting user authentication across multiple applications.

Key Requirements:
- Develop a Windows Service to implement a floating network license for my existing VB.NET apps
- Integrate user authentication within the service
- Ensure compatibility across multiple applications

Ideal Skills:
- Advanced knowledge of VB.NET and Windows Service development
- Experience with implementing user authentication systems
- Prior work with floating network licenses

I have some preliminary code written, but I need a professional to help me fully implement it.
