Amazon EC2/ FFMPEG

We are looking to encode videos on EC2 (Amazon's web services) using ffmpeg. Need freelancer to: 1. install LAMP on EC2 2. install ffmpeg and any dependencies, including x264 codec 3. Final application workflow: 1. user uploads file and can change video encoding quality settings in kbps (simple HTML browse and input fields along with an upload script in PHP needs to be created as well); 2. video gets encoded to H264 2 pass MP4 at quality setting passed by user; 3. encoded file and source file are copied into S3 bucket; 5. Thumbnail of video is created and placed in S3 bucket; 5. only admin or variables that we need to be able to easily change are the ffmpeg settings/profile; 6. final test of completion will be mpeg or avi uploaded to application. Process needs to be scalable to handle multiple requests and perform well--if it is necessary to have multiple running EC2 instances, then let's do it. Let me know of any questions. 100% of payment upon completion or escrow.
