Marketing is a big deal. Take a look at sites like
or Date-Check. How the fuck do you stand out from that crowd? And if you ask those that stick to advertising online (vs rolling tricks in the casino bars) you generally get 50% success rate on appointments (it goes both ways but your moneyed conventioneer has meetings and dinners to attend and maybe they got the sniffles or lost their cash in a machine, tables, or sportsbook). If you plan far enough in advance, you'll have a better time if you can get some of your current clientele to visit you while you're frolicking in Vegas.
