Good paying job with tattoos and piercings?

I love piercings and I dot have any tattoos yet but plan on getting them. I love the way they all look and I was really worried about getting anything done because of future employment/career. I am attending college and not sure what I'm going for yet, psychology (child/abnormal), business/accounting, or criminal justice. I reallllyyyyy want to get more piercings and get tattoos. Are there jobs in these fields that I will still be able to do and get paid well? Thanks.(:
