There are a number of providers that have IG accounts as well. They post pictures just like an IG model would. So, are they not IG models? But I guess the OP may be looking for IG models who do not advertise that they provide, but they do under the radar. I imagine there are some that if you slide into their DMs, they have a price. And, if they do, it's probably very high end. But who the heck wants to slide up into their DMs to get bitched out by 90% of them?
