I don't know of any 135 operator in the Northeast that operates single pilot in any equipment. Unfortunatley most customers insist on 2 crew, and if you are working for anyone worth their word, both pilots will be 135 current.
With your time I'd check into some of the operators in TEB, HPN, or FRG. You'd be a good candidate as a qualified SIC.
PM me, I can give you a few operators you might want to send resumes to/visit.
