If you're going to reproduce old art as a tattoo then find a tattooist who is very good at photo realism.
On the other hand, if you're looking for a one-of-a-kind piece of art - then don't even think about a "design service". A truly good artist will make a truly good design and then be interested in tattooing it. A large percentage of tattooists who might try to reproduce someone else's original work of art will do so only because they're hungry - not necessarily because they are capable.
