All the people recommending hiring an escort for FMF (or whatever scenario you seek) is that in all likelihood the experience will be dramatically less fulfilling than finding someone "in the wild." For one, it's not only about sex but about the whole process of seduction, which you miss out on with an escort. For another, unless you are paying her to hang out with you for HOURS and HOURS before getting down (an expensive proposition), you will miss the chance to get to know each other and build a little chemistry. There might not be any chemistry at all, which you discover after you've forked over several hundred bucks already.

Paying for sex can be fun, if you're lucky enough to find the right one, but can also feel sleazy and gross and demoralizing. It's a poor substitute to the real thing, frankly.
