Online community script

Hi. I need a script, I don't need you to develop one. I need an exsisting script. 1) Social Network Script like Myspace , Hi5 etc... 2) its in php and mysql 3) if its an open source better as I willf ind support, and you still get a good feedbacka nd payment for referring me to the website that has the script. 4) if you have one that you bought before , please let me know your price, also if you have one that you developed before. 5) I NEED TO SEE A DEMO and the funtionality list. 6) SCRIPT SHOULD HAVE A TEMPLATE SYSTEM OR THE LAYOUT SHOULD BE EASY TO MODIFY. (if its similar to the OpenRealty, oscommerce, Zencart creloaded templates system much better, as I am familiar with those) 7) PRICE IS THE IMPORTANT FACTOR AS IT IS THE SCRIPT QUALITY. Good oportunity to get a good feedback, and please don't post bogus bids or anything that doesn't have a demo as I will delete them. Thanks David
