Adult Website Specialists

Hello, Im looking for a privider who is a specialist or worked on adult websites that knows how to implement pay to watch live cams, private members areas with online chat and so forth. I am looking to develop a super directory site that will involve various streams of media such as cams/chat/images/videos for "models" to profit from, and take payment via sms or credit/debit cards. You must be familiar in this field - if you are not, do not reply! Be ready to show me links of sites you have worked on. Thanks Rakesh
