hey george - head over to tidalfish -
http://www.tidalfish.com/forums/ and check out the mid-atlantic offshore angler forum.
you want to either respond to a post that says "LOOKING FOR A HO" or create your own post that says "LOOKING TO HO".
something like this thread:

a "HO" is a hands-onboard.
you need to be careful about "paying" the captain for the trip. there are laws that could potentially classify that situation as an unlicensed charter...and apparently the USCG has been cracking down on those this year.
as long as you volunteer to help cover expenses, that's OK. that captain cannot make paying, or even covering expenses, a condition for bringing you along.
there's some good folks over at tidalfish that enjoy bringing HOs along. good luck.
