Create presentation for my youtube video

I need someone to create a beautiful animated PowerPoint presentation for my youtube video that I can attach with my voiceover to create a complete video. I would provide an audio script (in Hindi) and you would have to create an animated presentation for it and mark the points on script for playing the animations. It is very important that the bidders know Hindi language. NOTE : I would send a test job for quality check as I am looking for a really long term association here. Someone who can also do some content writing and audio script writing will be preferred
