How quickly can a voice-over deliver?

In general I can deliver within 24 hours on working days (Dutch time).

For projects that take more time, it can help to agree in advance when the session will take place, so I can reserve time for it.

Some days I spend the whole day on sessions out of the house, recording in other studios. (And very occasionally I am not in the studio for a few days, but in a forest, on a mountain, at sea or on a beach.)
