I would not recommend trying to use another artist's design. There's about a 90% chance that a quality artist won't want to do it, and a tattooist who would wouldn't be up to the task. Meantime with respect to traditional in your immediate area here is a very short list:

there are tons of good tattooers that do amazing traditional,
maybe you could find some tattooers that you like and see if they do conventions near you,follow as many tattooers that do the style you want on instagram ,
IG is a great place to do research and contact tattooers.
and this tattooer in Argentina, does he travel to conventions ?
