A custom cabinet maker and about $1500 for that setup unless you are doing the whole kitchen with him. Even a semi custom cabinet line that would offer that would want about that for the appliance hutch.

What would be a fair cost if one were having the cabinet maker do it as part of the total cabinetry being built?

The pocket door mechanisms do take up quite a bit of internal space. I'm not sure where the drawer above is mounted, because you typically have false sides that the doors slide back into, and the drawer hardware mounts on those false sides. I think I see a big of a cabinet bottom peeking out, which may mean that they used bottom mount glides. They are not typically done with a bottom, as it messes up the "hutch" type look to not have an open bottom sitting directly on the counter.

This particular 15" Deep appliance garage cabinet with the lift up pocket door was right around $1100 from my custom cabinet maker. It had similar pricing from several factory lines. The small job paint/stain set up fee is a couple of hundred unless it's a color that is getting sprayed on another job in the que, and you can wait for that to happen. You'd also need to wait on installation for a time slot that could be squeezed in between larger jobs.

They have to be integrated into the cabinet design before the build, as a single custom unit. They don’t leave enough room for countertop appliances as an add on because the whole cabinet has to be a custom height to allow that to happen. And that is why the whole setup is so expensive.

The glides have to either attach to the sides, or a cabinet bottom.

Make sure your coffee maker will clear the top of the cabinet. It probably means you will need to make the cabinet above it higher off the counter. Ask me how I know this

^^^ And that’s exactly why this needs to be custom! The glides mounted on the side will take up width in the cavity. The bottom mounted glides take away height. The roll out tray itself takes up height that has to be accounted for in either option.

The standard 18” between the counter and upper generally is not sufficient to have a tall appliance like a coffee maker or mixer reside in a roll out like that. That means a custom height. Which also means that the rest of the wall cabinets will need to be a custom height to align properly with the custom cabinet.

Everything is interrelated and it all has to be designed as a whole.

I had a roll out drawer installed for my microwave. My cabinets were designed with a garage for a microwave; subsequent to installation, I discovered that microwaves are should not be housed in cabinets because they cannot vent. A company called Art of Drawers designed and installed a rollout drawer. The cost was about $250.
