$700 y r u interested
When you consider the prices of lesser porn talents that play for pay out in Vegas, like Teri Weigel, it makes me realize how much of a lie your story is. They (pornstars) charge MUCH more than that, and given the fact that Jilly Kelly is pretty big in the porn world, with her own production company (that does pretty well), I doubt she'd let you look at her all night for $700.
$700 per hour, maybe.
