Joomla CommunityBuilder site login with facebook and twitter

Hi. We are looking for a Joomla 1.5 CommunityBuilder site login system with the following functionality : 1. User can Login with Facebook or Twitter or 'create new user'' 2. If this is the first visit to the site : 2.1 the user logs in with Facebook or Twitter then (after authentication) they are asked to enter e-mail address to confirm. 2.2 the user is shown their profile picture and asked if they want to use it on the web site, 2.3 they are also asked for their permission for the website to post updates to their facebook or twitter profile. 3. All login data is synched with CommunityBuilder. 4. If user logs out, the next time they login using Facebook or Twitter the system already knows who they are and automatically logs them in. 5. while logged in their profile picture can be shown on the page and they can post links to the article to their twitter or facebook site with 1 button. **We currently own FCBConnect and have seen jConnector - so it needs to be a lot better than this. Important notes : [login to view URL] login should be AJAX driven all done without moving between pages. (except facebook/twitter pop up for authentication) [login to view URL] login should use AJAX to check for username duplications, email's, drop down list selection and CAPTCHA. [login to view URL] to twitter and facebook using one button must be easily configurable from the backend. [login to view URL] modules / plugins / css are developed for this integration, they must be provided with documentation include comments in the code provided. [login to view URL] end entering of API keys and return URLs must be easy to use. We expect the following packages : p1. Full functionality description p2. Working Site with backend access to us p3. Installable module/plugin zip and documentation Finances and payment We will escrow 100% at the start of project. You must set up a server and demonstrate it working and provide above packages for full payment. Thank you
