Shipping cost per product

Hi,

is there any hint for a plugin or workaround to get shipping cost per product?

as we use different partners per product we would need the shipping cost defined per product and summarized in the cart. e.g. Product A with 5,-, Product B with 7,- and product C with 10,- should summarize with 22,- shipping in the cart.

any ideas? 

thanx and regards
