Canada: different tax brackets and different shipping prices

[summit61]

Hi,
I Basically have 4 different tax brackets (Ontario, BC, The rest of Canada and The US), I have 4 shipping price zones (Ontario, BC, 7 Territories and 3 other Territories), plus USA (where I need people to call for shipping costs). Then there's the rest of the world where I currently cannot ship to. and I have 4 different weight brackets.
I tried creating the zones and tried to use Zones Table Rate. The problem is one Tax Class is needed for all the zones and I need different Tax Classes for different zones.
Is there a module that can help me?
Please help.

Hi,
As no one replied I guess there are no modules that can help me.
Would any one think of a way to achieve this?
Any help would be appreciated.
Thanks.
