Amazon API programming

This project is to make use of the amazon buckets and file system via API. Steps Page 1. User uploads file - probubly an image or video. User sees a loading image while uploading. Then is pressented with 'Success' 'Fail' On the back end. - We need to make sure there is error catching. - Log all info that comes back into a db table This can be programmed in PHP or .NET. You may use MSSQL or MYSQL I would like two versions of the software. One web and one stand alone software. You may bid on one or both versions. Please let me know what version you are bidding on. If you know the Amazon API then this should not be a dificult task, but I am concerned about the overhead on our server, so the programmer will need to uderstand and explain to me the best methods to minimize overhead on server. Thank you.
