Good day, my name is Juan and Im willing to accomplish the task that you're in need of.
First of, thank you for such detailed documentation, usually we receive poor information about the project and even bidding is a risk for us, however this is not the case.
Personally I'd code this project in C# or C++, either ways I can work fluently and without any big issue.
If you believe im able to finish this project, I'd truly appreciate if you could open chat beforehands as I've a few questions, for example.. Do we need to implement any sort of hwid/licensing on the application? Do we have to Obfuscate the project? (even if we're giving source, some clients asked me to obfuscate a RELEASE).
Have a great day. I'll be patiently waiting for you in the chat.
