How traditional? Some American takes on the classic Japanese style tend to use more colors & deeper tones, and that takes longer & therefore more costly. This isn't a dis on the style, just a commentary. I've heard that, just like with American style pizza having become popular in Italy, that style change has made it's way back to Japan and is gaining a loyal following there.Expect to pay ~$1k for a half-sleeve, maybe a little less if you do gray/shaded water and clouds or other background art. A shaded/grayscale dragon versus fully colored should also make the work cheaper.I'd also guess ~10 hours of work, so 3-5 sessions at an assumed $100/hour.
