I am needing a web site and backend developed that would be almost identical to [url removed, login to view] in that it allows people to register and create their own profile and maintain account information that allows for various levels of access (ie. guest vs. paying members); allow visitors to search within a radius of a specific zip code (this will be very regional in scope); has matchmaking searches and selection criteria for visitors to browse existing profiles. I would like to support messaging between profiles but only paid customers can message but guests can reply only. Choosable "must pay" sections. Validate email address for guest account.
