Research is your best friend, check out the artist, check their work, don't rely on online pics they can be pinched off other websites. Go into the shop and talk to an artist, talk to several and don't just go with the first person, ask if they have done coverups before and you want pics of them! If it can be salvaged then they will tell you that. I don't have any personal experience with removals, but they are painful and costly, google tattoo laser removal and check out the images.
