Regular body shop rates around here (N. Idaho & Spokane) are $54-$60.
Specialty/resto/hot-rod builders are $90-$125.
Materials charges are around $28-$30 per hour.
For spraying out a customer's paint as a butt-match on a hood, you'd be around $450-$500.
If the OP has nothing but the paint, and no experience, it's well worth $500 to do it once and professionally.
As he hasn't answered my questions, I'm hesitant to expound further...
