I started looking for one local but then just wound up sending mine to Ken at kallenshaanwoods.com Inexpensive, great work, quick turnaround, pay shipping only one way. I doubt if anyone around here (Long Island)will touch anything for that price.
There is one place in medford that laser engraves many things like trophies and such that might do it but probably hasn't done it yet. Wood pens are virtually unknown around here I think. I've haven't yet met anyone, pen collectors included, who have seen or heard of a custom wood pen. (Shhh...that's a good thing for us).
