Color E-ink Dashboard >15 inches.. Which price?

I'm looking for a kitchen dashboard, like the Skylight Max, to divide family tasks and plan the day.

I'd like it to be a color e-ink display, even though I can't interact with it, but it should be able to automatically update every hour (if events on Google Calendar change).

I need it to show events for the entire week.

I've seen many designs here, but since I'd like it larger than 15 inches and in color, I was wondering if there were any cost estimates for this.
