PHP page for AWS S3 file retrieve

We are looking for a developer to create a simple php page hosted on our webserver (dreamhost) that: - Create a connection with Amazon S3 Bucket - Retrieve the file list saved in the above mentioned bucket (it cointains just high res images, archived in folders and subfolders) - Update a MySQL database with the new file list (each file should be a record in DB – images no more present can be deleted with their thumbnails) - Create a low resolution thumbnail for each new image in the Amazon S3 bucket (listed above) - Store (in a folder) the thumbnails in our webserver (no AWS) - Display a gallery of low resolution images in a page using the same folder (album) structure as the AWS bucket (folder may contain a preview image chosen randomly among images in the folder) - Images displayed must be linked to original file on Amazon AWS (therefore contain a pre-signed url) The project must meet the following: - overall gallery page should look like iPhone/iPad/Android gallery - it must be compatible with any browser including smartphones (responsive) - output page must be w3c valid - code must be commented The project should: - Be completed (and sent to us) within 10 days from the hiring - Run on my own server (We will use Dreamhost as server) - PHP 5 - Contain a dedicated configuration file or section at the beginning to set - AWS Access Key and Password - MySQL Address, UserName and Password - Not contains flash and should not require any plugin installed by users Please note that: - AWS bucket is not public, so a pre-signed url is required for file download. - The code can be re-used in other project - The output of the task will consist in the PHP file(s). The work will be accepted after code review and verify its compliance with the above guidelines.
