Commercial ''dating'' Web site

I need a Web site developed. It will be quite similar to an out-of-the-box matchmaking/dating site, so I have no problem if you start with OPEN-SOURCE code for such a site, then adjust to my specifications. If you consider it more prudent or cost-effective to start the site from scratch, that's fine, too. I'm looking for a commercial equivalent of a dating site, with suppliers and customers being matched up automatically. Full details are in the attached Scope of Work. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Must run on -ANY- Web browser on -ANY- operating system. This includes the Admin interface. I'm inclined to have it developed in an open-source language such as PHP, but am open to recommendations. If you think it would look great as a 100% Flash site, for example, I'll consider that, too.
