from bare metal up "material cost"

Hey guys ... I am in the early stages of having my 68 Barracuda painted. I originally stripped it to bare metal myself and had plans of painting it myself, but life got in the way and might be hiring a guy to do it.
so my question is I got a rough price on the cost of materials ( everything needed from bare metal up to clear) including sand paper, masking tape, sand paper etc... my potential painter told me $4000 (Canadian).
The car will also have the jams, inside doors and trunk painted also.
I thought it was high, to you experienced guys what do you think?
BTW.. I have seen 2 cars this guy has painted and they are like glass.
Thanks
