I want to find some foreigner friends

All right mate,
I want to find some foreigner friends nearby Seoul city to introduce Korea culture.
Of course, I'd like to talk everyday life with English each other.
I think that it's killing two birds with one stone each other.
Anyway I am working at foreign company as a designer.
The company is very famous for semiconduct in USA.
Actually I used to work at "S" group company which known every people in Korea. But I had offered for better jobs with current company. I have many used English since I joined this company and I have felt nessessity of English.
In my company, I am spending good time of my days designing with variety foreigner customers to do my jobs.
At that time, all kind of discussion had talked English to do my work.
So I really need some foreigner friends to get my better communication skill.
Are there any foreigner friends to find a Korea friends?
Great thanks.
