Large file upload to S3 (PHP/JS)

I need to allow users to upload large files to my Amazon S3 bucket. I'm looking for someone to create a PHP / JavaScript project that will present users with a "drop files here" box on screen. They can select one or multiple files and when they click Upload, the files are transferred directly to my Amazon S3 bucket. The files should go directly to S3 and not be stored on my server first. The user page should: - allow files to be dropped on to the upload field or selected after pressing a button - show upload progress - show success message or failed error messages The script should: - work with large files (2GB+) - utilise Amazons multi-part chunked uploads feature - automatically rename files to ensure duplicates are not overridden - allow me to define how many files the user is allowed to upload - allow me to define which file types are allowed - email me when a file is completed, including the original filename and the new filename This project will be used in an existing website, but you do not need to integrate it to the site. It just needs to work as a standalone script. For info, the website already utilises: - AWS SDK for PHP - PHP 7 - jQuery 3.2.1 - Bootstrap v4 beta 3 You do not need to use any of these utilities, it's optional. But they are available if you want to use them. Also, the final project should include instructions on what CORS or IAM settings I need to implement in AWS S3.
