Kids animation video

Hi there, I am looking at creating a 3 minute kids video cartoon. I would send you the storyboard with rough sketches for each scene, detailed description of what's happening in each scene & the full script. I have designed the characters on paper but you would have to create them in animation (they are just going to be very, very simple). I would quite like to do the voice overs myself if that is possible (how can we arrange this?), and I will also have some music to put in that I would give you as a digital file. And then I would want you to provide the complete animation from that, ready to watch. I am hoping to create a series of these if all goes well, so hopefully I will have more to come! Can you provide a quote please if you are interested? Thanks.
