Advice on Korean forums/blogs/internet groups

Hi! I'm working on a personal shopping platform based on international goods. Currently we have been getting a lot of shopping requests for Korean makeup, and have not had enough personal shoppers in Korea to keep up. Does anyone from Korea know of any forums (similar to SUpost), groups, or even Universities, where we could find people who might be interested in helping others shop? They would be paid for each package that is sent out.

Any advice is much appreciated! Other ideas are certainly welcome!

Cheers,
Andreas
