I offer gift certificates throughout the year. The people who have used them have been so happy that they return and do more workshops with me. You can see a link on the top of my home page and here as well. And you can always contact me if you have questions.
Aside from this blog, Shoot New York City also has a newsletter which comes out twice a month that you can read at your leisure. I started writing it more than 5 years ago and it provides tips and information about street photography, and of course NYC! You can subscribe here.
