hi

I've come into a strange situation. Quite a big studio has asked me how much I would charge them to create an animation similar to the citroen dancing robot add. (not as high quality and no compositing into life footage involved) Basically something like a robot bull running on a black background and transforming into a racing car. 20sec long.
Unfortunately I have no idea how much one would charge for something like that.

!!!please help!!!

note: saying give me their contact and I'll do the job for you is not help

ok found something that looks similar to what they want. A little less detail, hostility and a bit more organic, but that's the look.
