Canoodle.com similar site dev

We need a site to be developed for dating & social networking purposes.
We already have a complete HTML/CSS/img/Js design, which is very similar to Canoodle.com, and we need only an admin & user backend to be developed and integrated into design. The design will need some modifications and changes (mainly CSS and some imgs), approx. 3-4 working days.

Site has to be very secure, scalable and fast, with a lot of Ajax.
Backend should be developed in PHP (Zend, cakePHP, or CI ) or Java (Liferay,...), but NOT Joomla, Wp, Drupal, or similar.
The site itself doesn\'t have many features, but they have to be well coded.

Main features are:

- standard&advanced member search (search results in gallery / list / mini profiles, like on Canoodle)
- matchmaking (by location, gender, interests, etc.)
- meet me (please refer to Badoo.com/encounters for this feature)
- messages (inbox, send, sent, trash)
- events (search, add; I\'m in / maybe / Not come buttons)

Other features:

- user actions (send message, rate, wink, favorites)
- similar profiles (If you like this profile, maybe you\'ll like these as well... )
- location set (when this is set, all members and events are displayed within this location)
- multilingual
- homepage personalization displays (multi-box, with: Who viewed me, Who winked at me,...)
- I\'m Free for ... (coffee, lunch, dinner,... when this is set, other members from my area are notified about me being Free for...)

Please post your most accurate quotes and time frames. We will choose the one who can deliver the fastest.
NO advance payments, NO copy-paste bids, as they won\'t be answered.
