28879 Cloning site and add more

Hi, I'm looking at creating a site similar to the ones below but then add on MORE features. [login to view URL] [login to view URL] [login to view URL] All three of these have features that I like. If you go to these sites and know you can duplicate it (all features) let's talk and I will go into more details what I need. But please again go over these sites before replying. I am not posting all the details yet, because I only want people who can actually clone these sites to reply as a PREQUALIFER. Also if you have made sites similar to this before, please send me a link to demos. Thanks, Calvin
