Bon Chance, mon vieux!
Hope all goes well.
Your venture brings memories of the old days when I had at least one person per week wandering into the office looking for the "ferry to Colombia" or a "cheap boat to Colombia." In those days the overlanders parked at the hippodrome and complained about the Zone police who chased them out of the Zone.
Hopefully, you can establish some reliable contacts to the South so that you can pick up business going the other way. (As some on this forum have discovered, there are still lots of sharks in the trade.)
Your map link made me try to find my old house. Got the neighborhood, but I'm not sure I have found the street.
All the very best!
