To run a 2MW you are going to need a lot of money, the infrastructure alone will need at least 150-200k per megawatt, and you will need to hire a professional to set up the network security aspect of the farm.

As for the permanent staff, you will need at least 2 trusted folks to take care of the farm, they will need to have a general knowledge about electricity, IT and know how to use screwdrivers.

If you don't have the time to manage the farm, you will also need to hire someone for that task as well, whoever person you hire to work at the farm will only change a bad PSU, replace a couple of miners' fans, change the filters and that's it, but when a breaker is down, or one large exhaust fan is broken, they will need to report that to the manager, the manager needs to call someone to handle that.

You can save up on the cost if you would build everything yourself, but I tell you this based on personal experience, once you go past 100-200kw you are going to have a rough time dealing with airflow/heat, and you will understand after it's too late that the initial design of your farm was actually wrong, and you will need to rebuild many things, so just take a short cut and buy the ready to install mining containers even if they were 2x more expensive than setting up your own.

alternatively, you can just sell your power to someone who has enough money, experience, and staff to run the farm, you can probably sell it for 3 cents and make 30k a month doing exactly nothing.
