large file uploader

I need a script which can be used to upload/ transfer large files (over 100MB too) on my website. I would prefer PHP based solution against others as rest of the website is created using PHP. Ideally this should be created using ftp and needs to show a progress bar while uploading files. After file is uploaded an email needs to be sent regarding this upload to the configured email address notifying about the new file. Although not a necessity but if this script could upload multiple files it would be even better. Do confirm in your bid if you would implement single file uploader or multi file uploader. This should be fairly easy job for someone who has already done something similar in the past. I need this quickly so if you have a working sample you have a better change to get this job. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
