Shipping Method by Categories ?

[ReyBlack]

Hi all,

 

I'm looking for a contrib. that choose automatically one shipping module if my customers add to their shopping cart one or more products that belongs to a list of categories.

 

I mean:

 

I have the following categories: cat1, cat2, cat3, cat4, cat5 and cat6 where prodcuts in cat1 and cat2 are specials and need an specific shipping method (for example a cold refrigerated one).

 

If my customers have no products from those categories (cat1 and cat2) has normal shipping method (or default, or cheapest, etc... whatever), but if they add one or more products (they can add other categories products too) from this cat1 or cat2 the shipping module must be, obligatory, the "special refrigerated shipping module" (or at least must be de choosen from all the method listed).

 

Do you know if there is a contrib to do that? If there isn't can anyone help me to create this to share it with all community members.

 

Thank you.

 

Note: Sorry, but my english is not too good.
