Those involved in the sex trade in Denver and the Minneapolis area are gearing up for some big business.

ABC News reports that prostitution will get a boost during the political conventions being held in these two cities in the coming weeks, and online ads indicate the industry pros are getting themselves ready.

"We know it’s going to rise," Vednita Carter of Breaking Free, a Denver-based nonprofit which helps women and girls involved in prostitution and sex trafficking, told ABC. "That’s what we’ve been hearing from women who are involved in that life."

"Republican Convention Party Entertainment Hostesses wanted," reads the headline of one "erotic services" ad from the Minneapolis area on CraigsList.org.

A quick search by wowOwow.com found another ad from Minneapolis titled, “Convention goer from DC seeks Asian.” The ad text says: “Coming to town with Republican convention seek attractive asian woman for week! It will be a five star ride in every way no expense spared!!!”

Another one posted by a woman offering her services says: “If you are coming to the Republican Convention next month and need a distraction I’d be happy to come by. First timer, nervous CD: ht/wt proportional, wm, safe, sane, professional working in st. paul, ultra discreet.”

In the Denver section, one finds the likes of posts titled “Support Your ‘Colorado’ Entertainers” (aka, prostitutes). Other women tout in their postings their proximity to the Pepsi Center and convention sites; “incall loft,downtown by pepsi cntr and coors field& convention cntr also.”

In another Denver ad, "Rebecca" explained that she was offering a special convention rate of $350 for two hours but to qualify, clients must "provide proof of dem. Membership." "Rebecca" confirmed to ABC that responses to her online ads had increased in the days leading up to next week’s convention.

In Minnesota and in Denver, victims’ groups are planning to distribute leaflets and other material outside of convention events. They are particularly concerned about young girls who might get “pimped out” by older men to the cities’ guests.
