If you want three different options, you'd need to use the built-in Weight Based Shipping for that. You'd first create the three separate geo zones in System > Localisation > Geo Zones, and then set all your product weights to 1 unit. You can then set up a "per item" charge in the Weight Based Shipping extension like this:
1:14.36, 2:28.72, 3:43.08, etc.
You can then set up
different per-item rates for each geo zone.
If that seems like too much work, you can get different per item rates without using weight with something like
Multi Flat Rate Shipping. That would let you create (and title) whatever per item rates you want for each geo zone.
