30417 Upgrade File Hosting Site

I own a file hosting site, MyShareFile.com. I wish to add some features into my existing site. New Features to add, 1. Upload progress bar (ajax) Show how many percent of the file have been uploaded. You don't have to write it from scratch – there are many open source AJAX progress bar out there. Like the link below. is The challenge how you implement it into my site. - [login to view URL] - [login to view URL] 2. Display delete file link on page or email after uploading file. Users can delete the file with that link. 3. Set download limits for various different size files ( less than 5MB – unlimited downloads, less than 50MB 10000 downloads, less than 150MB – 500 downloads, etc) under administration page. 4. Display file removed message on download page if files have been removed for some reasons (against TOS, illegal files – warez or adult file). 5. Display file expired message on download page if files have exceeded the download limits. Thank you.
