You really should look at two choices-get the tattoo removed by laser or go to a very talented tattoo artist and discuss options for a cover-up. It is absolutely amazing what a talented artist can do as far as cover-ups are concerned.
There is absolutely no reason to do thru laser removal then get another tattoo. Doesn't make any sense financially or aesthetically.
If you would rather not have the tattoo then look for a qualified dermatologist or laser center for tattoo removal. But know that it takes far longer, is way more painful and costs way more than getting a cover up. I had a tattoo removed from my ankle (not too big & went all the way around) and it was very painful, cost about $2000 and it's still not completely gone. I had to stop treatments when I found out i was pregnant and J. never went back for my last treatment or 2. I would have to go home after the treatment, put my foot up and ice my ankle. Not fun!
And there really isn't a scar like what you think of when you think "scar". The skin on my ankle is J. a tiny bit lighter than the rest of my leg. Not noticable at all.
