It can be very lucrative. Post Ads in "higher end" locations like P411. Get some pre-bookings. Don't stay in the same hotel more than two nights. Stay away from hotels near the Mormon Temple. It is Mormon country (VERY religious) and frowns on such activities. Don't use cheap no-tell hotels.

Police target the low end street prostitution, but occasionally do stings at the Airport, etc. Just screen properly. Don't get lazy.

Best of luck.
