Put ppt presentation and audio voicever together into video

Hi, >>>>>>PLS READ JOB DESCRIPTION CAREFULY BEFORE BIDDING<<<<< I have created a powerpoint slides and audio voice over and I need somebody to put it together as video. It shouldn't be more than 20 minutes. I will deliver audio files in 45sec - 1 minute chunks and your job will be to put voice over slides and deliver it as a 1 video file. There's extra bit involved, i will also need you to add a short 'testimonial' video that i will deliver, it is 50 sec video in flv format that will need to be added after around 30 seconds into video I need this done asap Thanks
