I will create a VB .exe file that runs a Windows XP which you can run under a VMWare or VPS.
However if you want something stable that doesn't crash, I would recommend all PHP that run under linux.
Information will be uploaded to a mysql server and you can grab using phpmyadmin.
I will provide free 15 day support post publishing the application, in case the site was changed or application was not functioning well.
I will create SQL table with proper engine and good tuning that you can grab large portion of data.
Data purging may also be needed if you want to archive old data to enhance application
I will delivery the whole installation in a Virtual Machine (Windows XP or Linux)
Cheers
