Networks

Is this going to be centered at a single or multiple site ? Do you want network experts at more than one site ? Too much information still needed to offer advice.

I've seen such where one person reports to the CIO and they send out techs (experts?) as needed. Since we can't know what skill levels or if you hire when required when there is more work such as moving an office to another location then the question can't be answered.

-> Beyond that I'm sure you are reading about the "digital transformation" in some companies where the office and the IT is being wiped out (as in demolished!)

If you aren't certain what specific is needed or how many folks you need to properly staff with network support, hire an IT consulting specialist to perform an analysis based on your available budget. Impossible to get a definitive answer on an internet forum like this.
