Hi,
I can do VB.Net and desktop application and its actually my first language and field. I have VS Studio Community 2015 installed here right now and MS SQL 2012 for the database. I believe that we will be using native codes for your project. But if you prefer I can use ASP. Net MVC too in C# to be able to have more flexibility in the UI.
The mockup that you have is almost complete and I hope we can have some conversation on how each form will behave and will relate to each other. I'll start with the database design to determine the specific fields and relationships needed of those entities, and then go to the UI side to build the forms. The last part is too integrate them to make them work.
Hope I can here from you soon. Thanks.
Regards,
Julius
