Pricing is always on the top of people's question list. The more details you provide the more accurate estimate I can give. On average, my flash runs between $100- $180 and custom work starts at $120.
Things that bump the price up are size - placement - likelyhood of touchups.
For custom work, I usually send a sketch the day before and if we need to make edits we can.
This also might be a good time to clarify that I'm not a stick and poke artist.
