Meet an escort girl

Let me, please, ask you a few questions, dear colleagues. I am coming to Rio on the 3rd of January for a few days, after that I will go to Buenos Aires also for a few days. I would like to meet some slim model-type, tall girls with pretty faces that provide full service including anal. I speak only English. So, I am more for escorts, I guess. Private apartments could be an option as well. I would like to meet maybe some pornostars models as well if they exist in Buenos aires. I am ready to take girls maybe for the whole day so they could be my Tour guides and translators during the day as well but I can't imagine what the prices will be for 24 hour. Could you please recommend some good places where I can find escorts that speak English and provide full services? What private apartment would you recommend to visit with the most beautiful girls? In what apartment do girls usually speak better English? Thanks in advance for any answer! I sent almost the same PM to a few senior forum members but I guess it is much more correct to post a new topic so other people could see the answers
