I have been analysing some financial data for a Russian client. Apparently according to 2017 figures the average doctor's salary in Russia ranges from about £400 -£800 per month, it is no wonder that these ladies are in and out, working for as long as their visas allow them to be in the UK. On that basis a girl charging £300 per hour can earn the annual salary of a Russian doctor (say £600 pm, £7,200 pa) in 35 hours work (say 2 weeks) and that is after the deduction of agency "commission".
