Full exterior paint on Class C cost?

I am wanting to buy an older Class C 25' to 35", 80's-90's. I would like to have all bodywork done as needed and a full professional paint job on it to give it the look that I want.

All black with some chrome decal detailing. I am aware of the big black box in the sun effect and what it does to the temperature inside.

I am curious as to approximately how many thousands something like this is going to cost for the paint job.
