Just how confident is Los Angeles property broker Erik Coffin that he can interest Chinese clients in high-end Las Vegas villas? He's charging $4 million a month for a quick glimpse.

It is not just any tour. The marketing push is set to start next month for these twice-monthly journeys that cost $250,000 a pop for a seven-day, jet- and Rolls Royce-chauffeured trip to the American heartland. Eight-person groups also will be offered consultations on plastic surgery, picking a child's sex and wealth management.

"It's already a win for us," said Coffin, 42, who employs 18 Mandarin speakers, almost a third of his staff, at Gotham Corporate Group, which recently opened an office in Beijing.
