Trying to figure out how i can set up different rates for shipping...

i want to have three zones, and two prices for each zone...

basically it would look something like this:

US:
Standard - $15
Express - $30

Canada or Mexico:
Standard - $35
Express - $40

Rest of US:
Standard - $50
Express - $60

any idea how i would go about doing it?

I checked on shipping modules... and a bit lost to be honest...
