Development of Website Login Landing Page Form

I am looking for someone who can develop website login landing page form . I am looking to launch a membership based online stores platform . All visitors should sign-in using this landing page form regardless of their source or referring url . The landing page form should be deployed to all website pages including all sub-domains on the website domain .The landing page login form should be integrated to incorporate the following social network and email accounts to allow users to sign-up or sign-in using their existing accounts for the following social network and email accounts : GoogleMail (gmail ) , Yahoo mail , Facebook , twitter , Blogger , Windows Live , LinkedIn , MySpace .It is very important that the landing page login form has some form or transparent / translucent nature which allows some form of visibility of the background content but with limited detail . I have the following example of the landing page form on this url : [login to view URL] I am looking for serious people who can design this and allow us to integrate it onto our online stores platform .
