Paper - Packaging - Printing / Paper Kinds Requests

I am planning to launch a wallpaper business and am interested in placing an initial order of 100-300 rolls. Could you please provide pricing details for various designs, along with the shipping cost to the UK? My goal is to start with a small batch to see what sells well and then place larger orders. Additionally, could you advise how many rolls fit in a pallet and if purchasing a full pallet would be more cost-effective?
