As Ken says, there is nothing like hand painted pinstriping. It is pretty durable and looks great. I have been striping for a while now, mainly on my own stuff. Everything I own has been graced with pinstripes. I like doing freehand striping the best to give it more of a "Von Dutch" look. There are stencil tapes available like someone mentioned. I haven't used them myself, but I have heard they work pretty good. Just about anyone can pinstripe if they have the desire to learn and want to practice it. Otherwise, stencil tapes might be the way to go if you want painted stripes. Just be sure to wipe the area down with wax and grease remover first. Be careful with that though, sometimes that stuff can soften your paint.

About finding the paint, try asking a sign painter in your area where he gets his paint. Whatever he is using should work fine for this. I stick to 1-shot brand paint. I think 1-shot has a website, maybe you can order it on there. I don't remember right now if they have the color your looking for however. Since I live in a pretty isolated area, I have to mail order most of my stuff. I have always had good luck ordering my brushes and paint from Eastwood. I hope this helps out.
