There is a firm here called GB Liners that is supposed to be good. We currently use them for storage. I think if you called the US company, they would farm out to a local one here anyway, but you could try.
When we move, we'll probably start by calling GB Liners as that's who we know. Good luck! We're hoping to move back soon ourselves, but I'll be having the baby in the US of A before we have that all worked out - this August. I just sent all of our paperwork yesterday, so now it's just the waiting game.
Sorry for hijacking the thread! Good luck with the move and let us know how it works out!
