Actually, you could spunk right into pretty much any of these chicas on location in Colombia. In 2006 - 2009 I had several, costing between 500,000 and 1,500,000 pesos, depending how soon rent was due (low end) or if they had just appeared in Don Juan (higher end)
www.revistadonjuan.com. The dollar/euro was 30% higher back then, so we're talking about $200 - $600 dollars for a "prepagos" company for dinner, a club or two afterwards, spending the entire night in your hotel/apartment and then breakfast the next day.
Initially thrilling, it got old after a while, like everything else. Still obtainable today, but it's gonna be $500 - $1,000 or more. In 2006, even Natalia Paris was available for 5,000,000 pesos (about $2,000).

Cash is king in Colombia and there's an endless supply of models looking for sugar daddys.
