How many hires needed to make a data department for a farm?

I’m currently 72% in the Data Scientist path.
I know a farm that has no data whatsoever… no engineers, no data collection, zero digital platforms, does accounting/payroll on excel spreadsheets, no local network.
For a setting like that, how many people have to be hired ranging from the bare minimum, to the practical, to the ideal, in order to go from just agri to agritech? And what proportion of fresh grads vs experienced experts?
