Looking at making a one click hosting website that stores all the files remotely using Amazon S3.

I need to be able to change via config;
S3 Account / Bucket / Upload Size Limit / Disallowed Extensions

The script needs to upload the file to Amazon S3 while showing the user a progress bar, the script then needs to present the user with a list of URL's for the file that it will get from the cloudfront URL's via S3.

The S3 account data MUST be secure.
You must have very good knowledge of Amazon Web Services to do this project.
