Add Facebook/Twitter/Google login on my ClipBucket 2.8.1 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. Please see attached file for all details, if you don't quote some information from the pdf in you quote i won't review your bid. 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... I don't want to use the clipbucket plugin. If that is your solution please don't bid! You can visit the site at [login to view URL] to see what it looks like today. Short Description: New users 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.
