Visiting the Roots of cacao in South America - looking for guidance

Hello!  I am heading down to South America in the spring to get hands on learning in the cacao industry.  My interest is primarily exposure in growing and processing of cacao beans as well as it;s cultural influences.  Thought to reach out to other cacao & chocolate connosseurs who may have some guidance or recommendations about such a journey.  

Thank you!
