Chat Appointment/Scheduling with comments/ratings for BuddyPress/Drupal/Joomla

We have a client who needs a Wordpress plugin that will allow registered members within BuddyPress to schedule appointments with one another by the day/hour accompanied by some sort of approve/disapprove mechanism, reminders and ratings. It would work like this... A wants to chat with B on Tuesday from 10-11AM. A would post the request to B. B would approve/reject and notification would be sent to A. Reminder notices would be emailed to each. At completion of the one-hour chat each would supply a 5 star rating and short comment that would be added to their respective profiles. Client is open to using an alternate CMS, such as Joomla or Drupal, so long as there is some sort of profile/social solution for the members at the site - like BuddyPress. That said, client would prefer to stick with Wordpress and within BuddyPress, if possible. Sorry, won't consider anyone who's within 1,000 miles of India - too many bad experiences. If you're within 1,000 miles of India, and place an offer on this project, guarantee you'll be completely and totally ignored. Yes, 'within 1,000 miles' also includes anyone living inside of India too. Our experience has always been best with vendors in Latin America/Central America and Eastern Europe. You will be given preference. Alternate appstack for customization? Perhaps a bridge from WP/BuddyPress and some PHP and GPL scheduling solution? Ideas, thoughts recommendations? Totally customized plugin for WP/BuddyPress? That's fine too, need a very reasonable price. In any case will need this delivered and perfect in 5 days MAX. Under no circumstances will any milestone/escrow/advance payment be posted. Payment on delivery and no other options will be considered. All work is done on one of our devservers or client's webhost. Won't work with any type of broker or middleman. You must be the actual coder. We work with individual coders only. We work direct with our vendors. If you're interested in this project, post an offer of $1515 and 5 days with a 33% milestone and we can discuss the details in the PMB. If you do not follow these directions, you're demonstrating you are placing a spam offer, you don't understand English and/or you can't follow direction and you'll be ignored, I promise. Thanks! Matt
