Sourcing agent for luxury packaging manufacturer in Asia

I am looking for an experienced sourcing specialist who has contacts with reliable packaging manufacturers in Asia
I need help finding a manufacturer for premium custom packaging for a home décor product.
The packaging should include:
Luxury foldable magnetic boxes
Luxury mailer boxes
Metallic foil printing
Branded tissue paper
Clear protective bags
Initial quantities will be small (around 20 to 50 units), with larger orders planned in the future.
I would like someone who can negotiate prices, verify manufacturers, arrange samples, and assist with shipping to the UK.
Please only apply if you have experience sourcing premium packaging.
