Question about setting different shipping costs to individual items

Hello,

Most of the items within my shop are shipped by various artists and organisations from different parts of the world, so it would be great if I could attach a different shipping cost to each item. It's too awkward for me to calculate these shipping costs by weight or country... I would prefer to use a set shipping price for each individual item. Is this possible? If this is unclear I can make another attempt to clarify.

At this stage I've included shipping in the price of each item (except for the items that I dispatch personally), but I'd prefer to add shipping as customers progress through the checkout.

I hope someone can point me in the right direction.

Here's my shop: http://beinart.org/shop/

You could setup an attribute "shipping" and make it required then set the cost for this attribute when you add it to the item what you want

Thank you. Can you please break this down into more detail (steps). I'm a bit of a novice.
