Require Someone for Editing my YouTube Videos [Math Background is Must]

I create YouTube videos. The process of creating videos is: Step 1 (a): Creating animation (without audio) Step 1 (b): Recording audio Step 2: Audio editing (remove noice, remove repeating voiceover, make voiceover good to ears etc). [I usually use Audacity.] Step 3: Synchronise audio with animation. [I use iMovie for this but you can use any software (for example, Camtasia) in which you are comfortable.] I NEED SOMEONE TO DO THE STEP 2 AND STEP 3 ONLY. It simply means that I shall give recorded audio and animation, all you need to perform step 2 and step 3. I need someone who has experience of doing such work, please show me your past work while applying for the job. IMPORTANT: Since my videos are about math, so you must have mathematical background otherwise you would not be able to perform step 3 effectively. You should apply if you understand math upto grade 12. To get an idea about the math involved please watch one of my video here: [login to view URL] Also, please suggest me how I can make my videos better so that viewers get great experience. For each such project, I shall pay you INR 300. I am paying prices at higher side because I want quality work. This is an ongoing job not a onetime job. Edit: Also, I need you to add some mild music in the background. Thank you!
