Fix Facebook and Twitter Login

Our website has (or had) options to Login with Facebook and Twitter. Our developers have worked on it, and they're really good, but for some reason they are having problems with this one, and we really need it working, so we are resorting to outsource this work and hopefully some other developer with more experience can save us! Please check out our site here: [login to view URL] (disguised to prevent coming up in SERP) We have currently removed the Twitter login because it was causing problems. We have two ways the users can Login with Twitter Facebook. I will try to explain: There are two types of users on our web site. Advisors and Customers. Advisors are the Psychics who are providing the service. Obviously customers are the ones buying that service. So both have different accounts. We also have other cases, such as: 1) Customer already has an account but just wants to start logging on with Facebook/Twitter. So in this case, we just need to ADD their Facebook/Twitter ID to their current account. Then, next time they come to site, instead of entering their email/password as they have always done, they will now just click "Login with Facebook/Twitter" and it will search database for their account, ADD the Facebook/Twitter ID if needed, and log them as normal. But they could still use their username/password if they want to. 2) First time customers who never had an account. This should be somewhat easier. No need to search for and use their existing account. Just setup a new one and they should be on their way. We should also have a second capture screen that asks them to setup a password for their login. Don't most sites do this? I think it's always good to have a password setup for their account. Please advise. 3) Advisor Connect to FB/Twitter: Advisors cannot setup their own account. Their accounts are setup through a different process which requires application and approval, etc. So they will always already have an account. In their account dashboard, we have a button for "Connect with Facebook/Twitter" which adds their Facebook/Twitter ID to their account so on their next visit they can login with FB/Twitter. But, I'm thinking they should be able to login from the homepage as well. We should just search the readers database table first. If found, add their FB/twitter ID to their account and then log them in, right? They shouldn't have to connect from within their dashboard. This may solve some confusion. There is also a "Publish to Stream" feature. After advisor logins in with FB/Twitter, it posts on the user's Facebook Wall or Twitter stream: "Advisor is now available online for a reading!" This option can be modified in the user's dashboard. They can select to automatically post this message or not. All of this is supposed to be programmed already, but there are bugs, and problems. We need someone that is experienced with everything I mentioned above. Someone that can understand everything we need as I described and can get this done for us. Since most of it is created already, hopefully you won't need to start from scratch and can just adjust the existing code to work properly. Please do not bid until you have read all of the above and feel you have the experience to handle this for us. We don't have time to keep checking and saying "no, it's still not fixed". We need YOU to test it vigorously until it works 100% as we described. Then when you hand it off to us it just works, we pay you, and we move on to next project : ) Thanks for your time and bids!
