Customizing a WordPress plugin: Client Upload

I need a coder/programmer who can customize this plugin: http://wordpress.org/extend/plugins/dlg-client-upload/ a demo on my test environment here: http://www.printedword.testsite.marolinedesign.com/ username: test password: password

We need these extra functionalities:

* Files to be downloaded only rather than pictures opening in a browser or PDFs opening in Acrobat etc.
* Upload Progress Bar to in 'real time' that shows how long is left, the current one is showing that an upload is taking place without indication of time left.
* 'Upload Complete' message to show temporarily. currently when a file is uploaded, the Upload Complete message shows, but stays in place, even when one goes to upload another file.
* Keep the original file name, currently when one downloads a file, a number is generated in front of the file name
* Make 'File Name' a required field as when one does not choose a file name, no file name appears in the main list OR automatically have file name be the original file name
* Confirmation for deleting files rather than delete straight away.
* Align layout of users screen as all of the file names, dates etc and download/delete are not aligned the same way, some are centred, others left/right etc.
