I dont know if prospective escorts should expect the same 1200$/hr as this person, this sounds very high.
Good SWE in Europe - $40k-$60k
Good SWE in US. . . . - $250k-$350k
300k+ is, from what I gather, very high for US, whereas 50k is more or less entry level in western EU. But take my impression as a data point (or a cluster), not the ultimate source of truth.
