Longest skis one can buy

I’m 211cm tall (6’11”), and I like skiing, however until recently I’ve not owned skis, I’ve been relying on rentals. I stopped growing only recently, so I’ve been looking into buying my own skis.

However being the freak of nature that I am I’ve not been able to find any that are even remotely the right length for me. Does anyone know a good retailer with my size? Or am I doomed to use planks?
