I can put feelers out and see if any of my local NYC shops are interested in having you around Monday the 20th. Should they contact you via the email address you post beneath the comic, or do you even want to be bothered? I'm pretty sure you'd rather make your own arrangements since I'm just some loony fanboy you've never met. Let me know your preferences and I'll attack it from my end.
You sound responsible enough. The hardest part of getting a live-appearance thing is selling it to the comic shop, and while I'm happy to be available via email (yes, the link on the site is the address to use), I won't have a lot of energy for making the pitch.
Ideally I'd let you pick the venue, and I'll interact with the shop manager as necessary (e.g. "let them know I'm a real person who will really be there").
I'd like for it to be in a nice-enough part of town that I'm not going to be fearful of getting there, and preferably it'll be a short cab-ride from my hotel (Courtyard Marriot Times Square, 114W 40th St).
The SECOND hardest part is making sure my fans in the area know about it. That's MY job. I can put a blurb up on the site easily enough, and it'll get seen by 14,000 Schlock readers world-wide. I figure at least 50 of them live in NYC, right?
Don't worry about the "Loony Fanboy Howard Has Never Met" factor. I'm pretty approachable, hard to offend (assuming you don't Touch Me In Bad Ways, or Act Like You Suffer From Tourettes, or Sell Me Into Slavery).
