Develop WordPress Plugin

I have a facebook application which I need converted into a wordpress plugin. The application can be seen here [login to view URL] It works like this: 1. User lands on site and popup appears asking them to connect via Facebook in order to see the content. 2. They click login to Facebook button and are taken through the steps to login. 3. The application then automatically shares the page URL, description and post image to the Facebook users timeline as a link. 4. They are then presented with a like gate popup after a successful share and must like the fanpage for the popup to close. The WordPress plugin must follow the exact same function and look. The text must be editable and the logo ,login button and fanpage like gate must all be able to be changed to suit the user as well as make it possible to use the plugin across several different sites. To see how the current html application works please visit the link provided here [login to view URL] and login to facebook and go through the actions to see how it works. This simply needs converted to work across WordPress sites and must work exactly as it currently does. $60 is the price to do this work as this should be pretty straight forward for an experienced coder. We have lots of work on WordPress sites with allot better pay so get this job right the first time and you will have months if not years of work with us. Thank you.
