Are you looking for the IT Support people who carry out the day to day maint and repairs of the IT hardware and software at the schools or the Instructional Staff who teach the various software and technologies? Your inquiries are rather vague.
If you want the IT Support people who maintain the hardware and software, but have no responsibilities for purchasing software or hardware and instructional duties, you will have to contact an Area Support Group.
If you intend on 'selling' software or hardware, then you have to deal with Project Managers in NDHQ.
If you want to contact Teaching Staff, then you should find the School directories.
