An animated video advertisement . For you tube and social media.

I have an idea for a short video advertisement.
There are 4 characters , a car and some scenery.
I would like the characters and prop to be 3d and digital.
The characters are based on the wizard of oz.
The witch , scarecrow, the wizard and dorothy ( although only dorothys shoes, legs and hand are seen.
The characters will be similar but not exactly the same.
I have a full script . Also two very short pieces of music to be added in the background at various points.
The music is available from you tube.
I would like someone to create the characters and then create this short video advertisement. Applying my script and directions plus music.
