You "filled in the blanks" perfectly and that gives me a good place to start.
To whom? I get that you are focusing on NY- and NJ-based companies. Presumably you have a strong technology and manufacturing portfolio to leverage. Both are good.
It's the "craving" part that loses me a bit. I see what you are going for but I don't see how you would use the statement as a targeting tool.
That is, the positioning statement is YOUR blueprint (and not copy). So you're telling yourself that you're going to target companies that target effective connections.
I'm not sure how that narrows the playing field for you. How would you segment your market - "those who crave" and "those who don't"?
The who and what work fine. I don't know your market well enough (perhaps others can chime in here) but I wonder if "graphic designer and writer" is a better frame of reference than "small marketing agency."
Talking out loud, I'm wondering if your sweet spot is 1-10 person companies. I wonder if the notion of "you're small and want to keep your expenses down and get me focusing on your account in a way that larger agencies never would" could work for you.
Benefit? Energize your online and traditional marketing mix seems vague to me. It suggests to me that your answer to Question #1 is "there are people out there looking for a way to give their materials more zip."
Is that the insight?
Supporting claims? You've been doing it for 20 years. That is good. Is there something concrete you can offer about your results? Some metrics? Solid testimonials? A link to your portfolio?
Give some thought to Question #2 as well. Presumably you are stealing share from some other graphic designer. Why should I switch?
You got me on a "rambling night." I hope these concepts challenge you to zero in on your unique selling proposition.
