Or you can never go wrong with Miami companions http://www.miamicompanions.com/ there are one of the most expensive but they will give exactly what you want. Talk to Paul and tell him what you are looking for (GFE, BBBJ, etc etc but, be discreet) and he will be honest with you. Hey they even have a private section in there web site that gives some great/interesting photos. Some of my most memorable encounters have been with girls from MC.
Hope this helps
