Facebook and Twitter Login Script

Looking for freelancer who is able to code me a Twitter & Facebook login script. Here is an example of what I need [login to view URL] Use this example ONLY for guideline. I would write a code by myself but I don’t have time for that so that’s why I am looking for freelancer. I would also use the script from the link I provided but it has some problems with cache/session, but I also need a slight modification. These are requirements of what I need: - I have custom build Twitter and Facebook CSS buttons which I want to use for Login and Logout and not to use the one offered by Twitter or Facebook - I need a simple variable e.g. $login which I can use to check if user is loged in or not. Here is an example: <?php if $login { ?> Logout <?php } ?> OR <?php if !$login { ?> Login <?php } ?> - I need easy implementation within other pages by including not more than one .php file - I will give you the ftp access to one part of my server where you can work on the script - I need simple variables to extract user first, last name, Facebook & Twitter ID, Country, Image, email etc… - I need that when user login/signup on my website using twitter or facebook to be redirected on a certain page on my website (I will give you the exact path to that page) where I will write the code to check if user exist in my database. - Also it would be great if you can write the code that way so it can be easily expended. For example if I decide to implement Google+ login it needs to be easily merged with this script. I think hat this project should not cost more then $50. Also would love to see those who bid to have already done similar projects with APIs
