Dance event website CLONE

Hello, I'm looking for a clone of this webpage: [login to view URL] The clone has to be modified a bit: - different background design (we will make the design) - different colour and maybe a different place of the menu buttons. - it should include an option to invite people by things like email contacts importer / facebook / myspace etc. We are a non profit foundation which works only with volunteers so it's important that we find a cheapest as possible solution for this project.
