what things needed to set up an Office IT (Computer) systems?

Hi all,

Can someone tell me or help me to give me some possible solutions on what are the things needed for a new Office. My new building (work office) is currently under construction and I am searching online to look for the things needed for a new building IT systems.

These are the things that I have on my mind:
– Server (MSBS 2008, etc)
– Email server
– setting up the computers and clients
– etc

Can someone help me to choose the best option in terms of what to get, how to set it up, etc.

Thank you IT team.

God bless
Tim
