This sounds too obvious but I imagine you have tried any local sawmills?
We
have one near us that makes up pretty much anything but that's no use to
you...
These people are in London and make custom built architecture but I have
no
idea of price or delivery etc. http://www.gardenarchitecture.net/

The sawmills is the place to go, just ask for roof latts, thats the wood
they nail the roof tiles on, just bought some and it's treated wood as well.
Well it is where I live, good luck
