I totally agree with the sentiments expressed in this thread: it is much wiser and cheaper to make one's own arrangements in Russia and other EE countries. I've spent a lot of time in both Moscow and St. Petersburg and I've never had trouble finding gorgeous women for a good price. The hotel lobby bars are filled with remarkable talent, approved and supported by the hotels themselves. It can sometimes be difficult to bring in an escort from the outside without greasing the palm of the doorman, but it can be done.
As far as danger is concerned, I have been confronted by some young toughs on the streets of St. Petersburg but my then (now ex) gf, a 5' 98 lb bundle of energy, cursed them while mentioning the name of a prominent Russian mafia leader and they went scurrying off into the darkness. So if a petite foul-mouthed Russian girl can take care of business, I hardly think a bodyguard is necessary.
