Hello. I already solved this exact task a few days ago... I can just send you the solution I have for half the price ($20), or write a new one from scratch so it doesn't look suspicious since you seem to have the same teacher.
I have ~7 years of experience in C/C++ and over 3 in C#. I also write some Python code and recently Haskell, so I can do the task easily.
Could you please message me to discuss?
I have briefly read the description on development, and I can deliver as per the requirements however I need us to discuss for more clarity on the details, deadline and budget as well.
