Hi, I've got version v1.3.9f

Can anyone let me know how I can set the shipping cost of each item individually?
The problem I have is that they accumulate to a very high amount.
i'm considering buying the manual also. Does it cover things like upgrading to new versions, changing the time displayed by the server and shipping?

Failing all of that is there anyone that can do some configurations of our shopping cart if we pay them
