How to collect a judgement in NY?

[David Kirchhoff]

what steps do i need to take in upstate NY to collect a money judgement i was awarded during an eviction for non-payment? it's been a couple months and they have yet to pay, after sending letters for them to pay as per court order. what steps do I take now? I have bank account information and know where they work. what steps do I need to take to go after that? would it be easier to just send to a collection agency?
