On the carnet (if you need one) ..
It will take about 1 week to organise a Bank Guarantee (if you go that way)
And another 2 weeks to do the carnet it self ..
You can do this before the start of the trip and have it dated for when you start the trip.
(the time I did this before .. well it was over the counter in London .. did the green card etc all in one day .. times have changed .. not for the better)
