Mass Youtube Video Converter from Pre-made Script

I'm looking for somebody to edit a code I have already that converts youtube to videos to an mp3 one file at a time. What I'm looking for is, someone to edit the code and instead of only having one video download at a time you can add another page to download "x" amount of videos at once aka a mass video converter. It would need a limit of "x" amount of videos at once with captcha. It will be very simple so not high paying.
