It's totally unclear what you want: buy such a keyboard, sell it, find a driver, study the details of the lay-out, ...
Anyway, without knowing or mentioning the exact model of the laptop for which the keyboard is intended, it's impossible to buy or sell it. So it's even unclear why you link to a picture from a seller.
