Where user will enter his email and then will browse couple of files (max up 5) and select them for update as long as user will select the fill the file the "convert to" box will open up having a couple of output formats (initially 5 or 10 however I should be able to add more formats in the select box) so when the user will select the "Convert to" format the file be be displayed below from where user can remove it if needed, After selecting a couple of files when user will press convert to button then all the files should start uploading and should also show progress of each file separately, on the same page.
And once all the files are uploaded the user will be taken to another thank you page.
The Interface of the page should be simple good looking and professional.
(I would like you to use php APC extensions for upload progress as I have them enabled on my server)
If you think you can do this please bid.
