Hello there, read your description and want you to know that I have been working into Windows app development for more than 4 years now with numerous projects in portfolio. From small mini projects to complex management Systems and other applications I have done it all. My projects include Transport Management System, a point of sale system in c# , Intelligent bio metric feature prediction System and many more. So I'm very much sure about your system. We can discuss further details in Pm.
Kind regards,
Faizan Ahmed
