Add facebook/google/twitter logon to a clipbucket site.

If you haven't done this before please don't bid! If you have done this before please describe what you have done and also provide links/details. I will pay maximum $50 for this project! I have a site that is based on Clipbucket ([login to view URL]) and I would like to add some features. I have already have a developer trying to solve this with limited success and I want you to fix it and clean up anything that shouldn't be there... You can visit the site at [login to view URL] to see what it looks like today. GOOGLE, TWITTER AND FACEBOOK LOGIN The user should be able to login with his/her google/twitter/facebook account. When the user login the first time a new "basic user" (like if you create the account yourself on the site) should be created. And you should be able to use ALL features on the site as a site registered user. You should also be able to change your username for the username you use on this site. The design should work in responsive design (computer/pad/phone). In computer mode should be graphical icons and in phone mode it should be text. If you have any questions please ask before you bid!
