Build a Website similar to imgur.com -

Hello, 5 stars employer here ! I want a website similar to [login to view URL] but in arabic and RTL direction. I want all the features that website have. Requirements: 1. Super fast loading time on desktop, mobile and tablets and optimised website, specially when querying the database. I really prefer doing 2 designs one for the desktop and the other with mobile subdomain for tablets and phones. 2. images sharable on social websites like twitter and facebook. aka using open graph protocol and whatever protocol needed for twitter to show the image on the tweet when a link is shared EXTREMELY IMPORTANT. 3. Implement porn filter EXTREMELY IMPORTANT. there are some paid APIs on the internet but if you could implement it without using external APIs it will be a huge plus for you. 4. A button to share images on Whatsapp app when viewing from mobile and tablets. TELL ME IF THIS IS NOT POSSIBLE. 5. use of a php cache system. like xCache or any good alternative. 6. obviously a very good comment system with the upvotes working without cheating. 7. implement hashtags and show the most popular hashtags on the side menu. 8. Control panel for the admin, and for the registered users, and enable registering through facebook twitter etc. 9. Add one plus eight and type the answer on the first line to make sure you have read this. 10. Ability to upload images and albums and choose whether to make them public or private, and the ability to write a title and description for each image. Title and description must be used in the meta tags etc aka proper SEO using those information submitted by users. Those are the INITIAL requirements. more might arise. You are bidding for the Programming AND the DESIGN of the website. I want a complete work here. though the design should be extremely simple. Show samples in your message. Don't offer a crazy price ! be reasonable. Thank you.
