That depends a lot on the escort. There is (was?) definately an underground of escorts who did it to supplement their primary income. All WOM, no on line ads, reviews, etc. Typical was five or less guys, one or twice a month each. One group in a Midwestern state had 4 guys, 4 escorts. Dinner for 8 once a week at an upscale restaurant, then rotate who went home with whom for the night. If I remember right it was $2K per guy per month (so $2K per month to each lady). Seemed to work well for them.
