Uploadify & Amazon S3

I need an experienced AJAX/PHP developer to complete a script I've been working on. The script is based on using Uploadify (a multi-image AJAX upload script) to upload image files to an Amazon S3 hosting account. That's essentially it. I have some sample code but I've spent hours trying to get it to work with no success. If anyone has done this before it should be an easy and quick job. I can send the script in its current state to any potential bidders if required.
