For the question, we have not more comments. 
because the customers are sell the products in their country. 
so, we have not more experience fo the sell skill. 
but every customer have a target in marketing. it is improtant for this. 
for example, 
1) customer will ask us what product is suit in their country? 
2) customer maybe tell us what product in their country, and ask us some suggestion. 
3) customer also ask us how to avoid competition, and how to find out a way for themself products?  
4) some customer also how to PK with current marketing. 

anyway, if you have any ideals please let us know.
