Hello. Here is all you need. PRO voiceover (200-400$), storyboard - isn't important if the same person will do animation, but if you need it too Storyboard - ($100), SoundFX 150$ everything else goes to animation...
But if you are interested on PRO animated video, i need more info. As something can be created within $250-750 range, everything else 1000-xxxxxxx range.
I'm pro and working in media industry over 18 year, so know my job and love it.
Sincerely,
Ray
