Marketing trade ?

Hello~
I am from Korea.
You know, the marketing is very hard for indie developer.
But if is my own country, i can do some marketing.
Famous community, My friends, Social, ETC..
But other country is very hard to promote.
So is there any developer who hope to trade marketing ?
If i promote your game, you promote my game your own country.
