I need some help with this idea. I am not a Zen Cart expert but am helping out a friend.

I want to setup 3 different shipping amounts for each and every product. That's all. I do not want prices based on UPS, or weight, or anything. I simply want the option to manually enter 3 different shipping numbers. 1 will be for Canada, 1 for US, and 1 for international.

He is willing to enter a different price in each box no problem but won't leave it up to UPS to get the shipping charges. Is there an app that I can install to allow different shipping rates for each product? If anyone can help me with this I will pay for setup, it just needs to get done. please.

Thank you
