Hi there - I'm Aly,
I've seen your post and I'm interested. I've had much experience in C# and I'd like to know more about the task ahead of us. If awarded, I can implement your GUI either as a WinForms app or a WPF app.. I can even implement a web interface if needed. I'd like to see a sample of text files that should be imported/exported. Don't hesitate to contact me so we can discuss further details.
Sincerely,
Aly El-Haddad
