Change upload script on my site from tesupload to uber-upload or other that works faster

Hi, I have a yousendit-like site ([login to view URL]) and currently we are using the tesupload script to handle the upload process /progress bar. I like the way it looks, but I have compared it to another site (a video site) we have on the same server, which user uber-upload to process the upload and progress bar. And the uber-upload is about 4 or 5 times faster. What I want you to do is install uber-upload or other script you suggest on my site and modify it to keep the look and feel my site currently has. It should be a simple task for someone who has done this in the past. I will give more details in a PM. PLEASE DON'T BID IF YOU DON'T HAVE A WORKING DEMO OF YOUR UPLOAD SCRIPT. Thanks!
