jQuery file upload script with progress bar

Needing a script that will allow users to upload ZIP/JPG/EPS/SIT/TIF/PNG/PDF files to our server. The script must upload a file from a form and give the user feedback of the upload through a progress bar - letting them see how long the file will upload. The script must not be in flash but must be in jQuery. The script must be secure and should not be able to give access to the end user. We can create a separate FTP only for this upload if need be on our server. The file that is uploaded should be uploaded into a folder on our website - in an FTP folder, and the folder should be name after the person whi is uploading for easy tracking of the uploads. So for example if the guy " John Smith" uploads a file - it will drop his file in his folder, called "johnsmith" on our sever - if he upload another file with the same name - another folder will be created called "johnsmith1" and then "johnsmith2" etc. The upload script has 3 screens - the form, the upload and progress bar to give user feedback (It does not have to be identical to my screens) and then the success screen, Admin is then sent an e-mail to inform them of the uploaded file, and admin can click a link to download the file - or they can go to get the file through FTP. Form validation - the form validation is described in my screens. ## Deliverables Please see my screens below to explain what is needed. You can see the working site and the script that is not working at the current page - see:[login to view URL] The must be a maximum limit of 600MB on the upload.
