Meditation & afirmation videos

I am looking for somone to make 20 meditation videos and 10 afirmation videos. These videos just need to have soothing meditation sounds with a tranquil video such as oceans waves, clouds moving around in the sky, a waterfall etc. The afirmation videos will be the same as the meditation videos just with added voice over of afirmations. Each video needs to be atleast 30 mins long so I can use them to run my classes.
