Need peopleofwalmart.com clone using Wordpress

Hello - I would like for someone to build me a wordpress site similar in functionality to peopleofwalmart.com. I'm not so much concerned about the theme/look being perfect, as much as the functionality. Upon completion, the site will have the following features: Website visitors can register manually, via Facebook registration, or Twitter registration. Members can login via username/password or Facebook login or Twitter login. Members can upload photos. Uploaded photos require admin approval before going live. All visitors can rate each photo with thumbs up or thumbs down. Rating is displayed as stars. Comments can be made by registered members or by entering a Name and Email address. All of these features above are currently found on the [login to view URL] site and should all be integrated into Wordpress using open source and free plugins currently available (no custom programming should be required). I am not asking for an exact clone of their site. Please let me know your fixed-price plus turnaround time to complete. Thanks!
