What are your favorite flavoring companies for concentrates?

[cafetero]

I am currently setting up a roaster here in Bogota, Colombia and would like to find which companies make the best concentrates for flavoring fresh roasted beans.

Question

Hy!
I know it is not related to the subject, but I would like to ask you one question, as I read that you are in Columbia: Can you provide me some contact details of green coffee suppliers? I am working for a roasting company in Romania. Any help is very appreciated. Thank you.
