Paint experts.... help estimating cost for 'artistic' paint/graphics

[TNH]

I've always had my vehicles painted in single colors, but for my next project I am considering doing something artistic with the paint, such as some ghost skulls or flames, etc.
The thing is, I don't know anything about the process of having it done and have no clue what this kind of work costs. Are there guys that specialize in this sort of stuff with airbrushes, and then you have a regular body guy do the clearcoat, wetsanding, etc? Or do most guys that do this sort of work also do regular paint and body work as well?
Do most of these artists charge hourly like a tattoo artist would?




I know this is more 'lowrider' style, but I thought these stripes were pretty cool...


I liked the way this Japanese fellow combined various styles in his '67 Camaro.....
