I found this guy through the dealer I did my recent ED with. As long as he has your flight information, I don't see a problem with him not being on time.
When my buddy and I finally came out of the secured area of the airport (where you hand over your passport to be stamped), there was an easel with a large roundel placard on it and an arrow pointing towards him. He couldn't have made it more easy to find him.
I implored him to check his email more often as it is the ideal form of communication...it would be better for his business!
