Needed contrib, many can use

[Guest]

I have attributes for almost all of my products, and these attributes chanche the size and wight of my shipping. I want to be able to change shipping cost based on changes in attributes. Is there way.

 

Ideas:

 

1) Using weight added to attributes contrib and have 2 attributes attached...like size A must choose weight A, size B must choose weight B.

 

2) Make an atribute set that includes 2 values (the attibute and the shipping cost) The shipping would be hidden from an option.

 

3) Any other methods, please post.

 

Possibly there is a contrib out there that works, please post. My store cannot work until I get this.
