WTB: someone who can make a "Progress Bar" for my site

Hey, please go to

When someone enters a video url on the site, it takes a while to get the mp3 download box to pop up. I want there to be a progress bar which shows how much longer it will take to convert the video to mp3 before the mp3 download box shows up.

i want it to look nice and sophisticated but also work properly.

thanks, please pm me if u can do this job.
