How do I look for a New York State tax planner in FL?

I am thinking of retiring in New York State and as such I am thinking of converting my rollover IRA into a Roth for tax purposes. I will be in a lower tax bracket when I retire, but perhaps not if you include NYS income taxes. But then again, perhaps NYS treats retirement “income” differently from earnings “income”.

Are there lots of tax and retirement planning professionals that are acquainted with situations like this in Florda? If so, what are the key words to look for?
