Hi Mike,
Unfortunately I do not know of any professional repair service companies in NYC, but you are certainly able to do the repair yourself at home, using [guide|2209|this guide] and the parts listed in that guide (and you'll probably save yourself some money too.)
However, if you need it done by someone else, then these guys say that they do iPad repairs, but I've never used their services: http://ifixny.com/ipad_repair_wifi_3g_apple_service.html
Happy fixing! :)
