Auto Facebook Share Script

I am looking for a professional to create a simple auto facebook share script for my website with the following terms: - Any user visiting the website will share the page (Title, image, and description) without knowing and without showing on his activity log. - Limit share per visitor to one share per hour (I should be able to change the duration from the script) - If the user is not logged in to his/her facebook profile then no action will be taken. - Clickjacking is not acceptable for this script, it should share fast while the page is loading on either desktop or mobile. - The script should not affect adsense code in any way. Please show a demo of a script you've already done.
