Finding European buyers companies?

Hello
Since I’m new to this community, I should tell why I’m here.
I’m from West of Iran. I can gather wild plants of this area and send them to European countries. The quality of the plants are great and I can guarantee that any company will like them, and we can make a long-term connection and business together.
Just I don’t know how to find a company that buys from me and how can I attract them. Can you help me to see how this process works and what should I do

I can gather tons of each of these medicinal plants:
Lavender
Hollyhocks
Water lily(Nymphaea)
German chamomile
Nettles
Common wormwood(Artemisia absinthium)
Thymes
Poppy
Yarrow
Hawthorn
Crataegus monogyna
Rosa canina(Dog-rose)
viper's bugloss  (Borage)
Tragacanth
Rumex(Dock)

Thank you,
