Hello.
We have been working extensively in windows standalone/Client Server application development using c#.Net for last 12 Years. Using both ODBC or MSSQL directly. Some of the project that we have handled are Time attendance, Visitor Management, Weapon Management System, Biometric PC Logon, Billing system for textile Factory, POS for restaurants & Cafes, etc and many more. Recently we converted / upgraded DOS software to windows OS with same look,feel and working.
Kindly check my profile for more details. I have worked extensively on the technology and the logic you desire to implement.
We can also work out to work on hourly basis if you desire. Kindly message me for further discussion.
Thanks & Regards,
Skynics Smart System.
