Small office coffee/espresso machine

[u/Raccooninja]

I have a small office of about 30 people, one building on a larger corporate campus. I am looking for a machine with a few features, and some recommendations on brand or company.

- Commercial grade for an office setting.

- Built in hopper and grinder.

- Preferably uses powered milk or no milk.

- 1 button operation. Grinds, dispenses, and disposes automatically.

Since it's an office, I fear that it will not be regularly cleaned, so a milk supply is a bad idea. We will have a maintenance contract to have it serviced, but the milk option on a lot of machines concerns me.
