I am a Long Island Realtor. I've done a ton of rentals in my career and would be happy to assist any clients you have moving to the area for purchase or rent. It looks like im too late on this one as I have just recently joined. But keep me in mind in the future!
There are plenty of realtors who can do the job. chances are the one that lists is not the one that rents it... I would interview a few and list with one.
