I need a model made to scale 1:5000 of a property measuring 170 hectars.

I am not too concerned about the material, but rather on having a fair representation of the elevation changes inside the property.

The model must be made 1:5000 because I have other pieces (paper & magnets) that will be tried on the model to study different positions/configurations, and these pieces are already scaled 1:5000.

Final product would be shipped to Calgary, AB.

The following coordinates define the land in google maps:
