Hello,
I am a professional software developer expert in Microsoft technologies
like C#, .NET, WPF/XAML, WinForms, WCF, EF, Linq, ASP.NET, ASP.NET MVC, MSSQL, SQLce even VB.NET, C/C++, web services, windows services and many others.
Based on the project description I can't estimate the exact cost of the development neither the technologies required to use so I suggest to discuss about the scope of the project or please send me a full project specification documentation to read.
Regarding a windows service application I have developed several services until now. I have also good experience with Windows Internals and low level system and security related to windows services. I can work and consult you in many ways.
Best Regards,
Patrik Fatoric
