Try finding an agent through a personal referral from someone you know and trust. If you can't then meet with three agents and see which one you feel most comfortable with. You want an agent that will talk more about what they will do for you then themselves and how great they are.
Unfortunately not in NY but when there is silence there are issues, usually. I would have your attorney or agent find out what the deal is before throwing in the towel. Assuming can get us all in trouble.
