Abrahams servant seeking a sign

When Abraham sent his servant to find a wife for Isaac the servant prayed for a sign. The servant asked God to send a girl who would offer him water and give his camels water also. Now I have read this passage a least 100 times and it just hit me what the magnitude of the sign was.
There were 10 camels.
Camels drink about 3 gallons of water at a time.
Wells were dug into the ground 20 to 75 feet or more and had steps.
These water jugs wieghed 40 pounds or more each.
It would take the equivelant of walking up and down a 20 to 75 story building with a least a 40 pound pack to give 10 camels water.

I say this was no small sign the servant was looking for. What think you? Is my thinking on this right?

 

What do you think the chances of finding someone willing to do all of that are?

 

In terms of each trip that would be true however it would take about ten trips to get each of those camels 3 gallons of water which would translate into 400 to 1500 feet 20 to 75 down and 20 to 75 up times 10.
