Actually, simple math shows that there's no way it could possibly be over $10K per day. Even if the den didn't take any cut from the cash, at $320/hour you'd have to be booked solid for 32 hours in order to get above $10K. Even if the girl had a 1/2 hour booking (at $220/half hour) every single half hour, it would take 23 hours of solid work to get above $10K. In fact, realistically, even your low-ball estimate of a couple of grand a day would likely be a well-above average day, since it would take 7 hour-long appointments to get above $2,000, even if the den doesn't take a cut, and I would expect that an average day would consist of 5 or less appointments for most of the girls at the den.
