site in wordpress clone

hi please check the details I want a very similar site to [login to view URL] - with all the same features and method of working. I'm wondering if this can be done in BuddyPress through Wordpress... of some other way. This is a small project - for the specification of the site - including the Technical Specification and how it will be implemented. ITs not for the actual build of the project. But a document covering how it can be achieved using existing open source technologies. budget $30 to $200 time frame 5 dayx max thank you
