Good lawyer for EB3-EB2 port

[ferment]

Hello,

I am looking for a lawyer to file 140 and port my EB-3 priority date to EB-2. I am a full time employee and since I pay for 140, I have a freedom to choose my own lawyer.
If any of you have had good experience in porting priority date, please send me the contact details of the lawyer. It will be convenient if lawyer is in the northeast region.

Thanks for your help!
