Careers for "punks"?

I’ve been wanting to get a mohawk for ages now, the problem is obvious – employability. I’ve spent the last 2 years in an office environment and now, even with “normal” hair I’m having trouble even getting a reply from prospective employers. So it got me wondering, are there any decent careers (so no game/music/porn shops, no tattoo parlours, or the like, either, please) that would allow me to flash my punk side?

(Putting this in social, as a lot of you will probably lol at this question ;-)

Cheers!
