Source code analysis (File contain trojan)

I am seeking a skilled programmer who can perform a source code analysis on a file that contains a trojan. The programming language used is C#. Although the file's current use in a production environment is uncertain, my main purpose for the analysis is to understand the trojan's functionality. Therefore, I require an experienced professional who is capable of identifying security vulnerabilities and comprehending the inner workings of the malicious file. If you possess the necessary skills and expertise, please contact me.
