Build a social networking system

I am looking to move my phpbb forum to a new host and add a social networking system to it. I have been looking through the options available and was looking to build a clone of [login to view URL] Please consider looking up the following software to give you an idea of what I'm looking for: phpizabi joomlapolis phpfox buddy zone e-friends dolphin vbulletin (with osdate or zoint mods) Also I am considering changing my phpbb forum to a vbulletin forum. Either way, I would like my forum to be connected to whatever social network system is built and everything to be streamline. I am on a limited budget. Also, I must move to a new host in the next 5 days, so you must at least be able begin within that time. I understand if the finished project takes longer, but I need everything (my current files) moved within 5 days, you can continue working after that. This is the first of a few projects I will have, so I am looking for someone that I can use in the future, depending on performance. Please only bid if you have experience with forums, being an expert php programmer is essential. Please explain why you would be best for the job, simply saying that you can do the job doesn't help me decide. Good luck.
