I have travelled many times to Colombia/bogota and agree with you. There are many low end places that are hit and miss.
So you should take my word of advice with the 2 agencies I recommended. There might be other agencies or places, but I know these two are consistent.
You could also try going to one of the high end strip clubs around the 82 with 15. Once I went there, talked to a girl for thenight and she gave me her number to txt her once I was out of the bar. They get into shit if their boss sees they are going away with a client. I txted her back and soent the entire night withher ata motel for only $125
She was gorgeous, but it happened to me once, so it is all about how lucky you can get.
Cheers!

Don't know much about Bogota. In Medellin just go to one of the mid range casas in Laureles, no bullshit no scams hot girls for $110k pesos ($55). At night hit a high end strip club, girls will be $170k at Fase Dos and a little more in La Isla if you do them in house that is. Lots of selection, super hot girls, good atmosphere but expensive drinks. With a little Spanish and some effort Medellin gets much cheaper, but if you're trying to avoid bullshit then this is the way to go. If you're willing to pay the bar fine you can pull the girls from the clubs and bring them home for the night usually for the equivalent of one hour with a girl in Toronto (again, this is if you're trying to avoid any uncertainty or bullshit....I've rarely had trouble meeting up with a girl from the clubs that I like and bringing her home at the end of her shift for $200k). Also, I've grabbed phone numbers at the clubs and made appointments for the next day with girls.
Medellin does require a bit of work I guess, but I much prefer that bullshit than the bullshit here in Toronto (namely having to go in blind off of some often heavily photoshopped pictures, plus the emphasis on time)
Cartagena has a couple clubs (Isis and Playboy - only been to Isis more expensive than Medellin clubs but super hot women) a freelancer bar called la Dolce Vita and has in the past had after hours clubs to meet girls as well. There's also plenty of girls hanging around the clock tower at night....just take them to a nearby love motel...they usually run about $150k.
