C#, .net, WPF tutor

I'm looking for an experienced tutor to help me grow my skillset in C#, .NET, and WPF. I'm looking for someone who has advanced knowledge in these three areas and can help me go beyond the basics. The tutor should have a solid understanding of .NET and be able to discuss, teach and guide me the best practices and upcoming trends within the technology. I'm not looking for any specific time limit, as my goal is to become a top professional in this space. I'm looking for an experienced tutor to help me with my development and teaching me how to apply it to real-world scenarios.
