looking for a centre/island cab for my boat

[insideout]

Hello,
I am looking for a centre/ island cab to suit my boat, or information that can help with building one.

This is my current boat, (green side console)


And this is the cab i would like to install (from white boat).

So is anybody clued up on how to go about it?? Or know any consoles similar to this one for sale?

Thanks, IO
