Alot of these IG girls could probably make alot more money if they went the youtuber route and did reviews for hair, fashion, beauty products.
I know somebody personally who's making a living off of it [not anything too crazy] but she pays her rent in apartment and all her other bills from it and only has about 70k subscribers. These IG models could easily do 5x that and can make bank [Im talking at least 2000 per promotional video, 2000 is being modest and on the very lowend trust me, companies are paying upfront fees to do the videos + a % of sales]
