Bookmarklet for website

I am looking for a bookmarklet to be developed for my website which is powered by wordpress and is mainly a website for videos. This bookmarklet should do: Check if a user is logged in on the website. If the user is not logged in then a login form will be displayed. The user should be able to submit this form without leaving the domain that they are on. When the user is logged in the bookmarklet should: 1. Slide in/pop up from the right of the screen 2. Populate a carousel of the 'main' images on the page. 'Main' images found on the website/or if it is a video sharing site/than the featured image,og image. 3. The pop up should contain the fields for: • A title • Description • Select category from drop down • A thick box for sharing on Facebook/which would be ticked automatically. The JavaScript should insert all of this into a [login to view URL] case it is a video,than embed the video with the description from several video sharing sites/youtube,vimeo,funny or die,[login to view URL] etc./. Should set the main image automatically as a featured image,video thumbnail. You will not be given FTP access to the site itself/because it is online and there is no excuses if the site goes offline for any reason.I will provide you with the theme that i am using,you have to provide documentation what has been changed on the theme and how to implement it on the website.
