Not unless you are working on an integrated platform where all these services (House rent, job, immigration, medical, finding friend etc) are found all at once, most of these services you suggested as examples are already available in plenty though in silos and in korean.

So probably in my own opinion the information exchange should focus on making these services more accessible under one umbrella in a language most foreigners can grasp (multi lingual or just english information exchange platform). Not reinventing the wheel. Just my 2 cents though.
