Depends on the tattoo artist and how much time and effort they put into. Just make sure you go to someone that is A tattoo artist and his place of business is clean. I have two tats and his waiting list is 3 months. I have no regrets but always remember, a tat is permanent.
Every tattoo artist charges different amounts. You will need to take your design and ask them. Go to a reputable shop and ask to see their portfolio. Pick the artist that you like their previous work. Definitely remember it is permanent so get something good. It is definitely addiction i have four and am going to get more.
Where I live they charge $100 an hour.
Artist charge by hour, size, and amount of color added. I have six tats. That one could range from 120 to 200. Depends on where you go. Check out different places and get some prices.
