You are going to see this sort of ads frequently in Korean Subway train.
What the ads is saying: we are specialized in marriage for elites, professional workers and high class people.
The market for in-between is quite big in Korea. Even you would hear of the commercials on TV and radios. Paying money for getting married with a proper partner is not an option for me. Because it's like buying love with money.
What I don't understand is that it's very widespread. I understand that it can be in some part od Korea. 

I don't know it's also seen in other countries but at least I think it should not be a normal thing.
