WooCommerce EXPERT ONLY!

I need some help with setting up shipping costs per item. I can't figure it out at all.

Example of what I need:

Cat lead $4 + Shipping $3 per item
Fish tank $8 + Shipping $6 per item

Total costs: $12 + $9 Shipping.

I also need it to add shipping costs per item if I want 1 or more of the same item.

I need an expert in this to get it sorted asap for me.

Thx
