I'm not sure what kinda thing you're after but judging on what I've seen - i think there may be better out there.. not that i know much about this kinda thing :P
There was an app created by a member of a different tattoo forum - it's a map of tattoo artist's near your location, it's for IOS and android i believe.
Check it out: http://thebragartlist.mobuapps.london/ :D
Go for it! I just wish I was closer to Philly, so I could have used@Mike Panic. The doctor I went to seems real thorough, however. Planning to visit Sarah Hurst in a couple more weeks to see what she thinks. If it needs more lightening, I'll do it but I think Sarah may go for it when this settles. She's done a lot of both coverups and corrections, so I'm in good hands. The body will heal, but at 64 it takes longer and it is harder to tell injury from age! Now to get the bike fixed....
