there is also latin life mates in bogota, dont know about their service. their are also two more agencies in medellin, but havent used their services either. one has an office in parkajeras (sp) in the main squaire.i think they are affilited with " a foreigh affair"
also a good idea to get on "amigos .com" before heading down, get to know a few people in the cities your visiting before going down, allways good to have contacts, just incase you have a problem, or need a friend.
