Fiction Audiobook Reader Development

I have a childrens story I want to put on Google Play and sell as an audiobook. But I want to use different voices and sound effects and music so it is more like a radio play that simply a narration. I need help blending all this together. I need someone with technical experience in audiobooks. Also I need to purchase sound effects like wind, rain, nature sounds that is legal to use for resale.

The perfect candidate enjoys fiction and understands the subtleties that can make the listening experience more enjoyable for avid readers. I look forward to seeing your proposal.
