I am a amateur tattooist and i have done a few designs .Iam looking to post them on some sights but am struggling to get replies.Dose anyone know any

if you use http://www.deviantart.com/ you can sell prints of your work on there. otherwise you can try http://tattoojohnny.com/ and http://www.tattoofinder.com/ but other than that studio's also buy flash from people, but you have to go into the shops with your samples and if their good enough, they'll buy them off you and use them in their shops.
ask for the shop owner when your trying to sell.
