anyone knows "Daniel Green" in NYC, the immigration specialist

according to my company. They are going to use this "specialist" for my green card petition. I am not sure if he is a lawyer or not. I vistied the law firm's website but can't find much info. He charges 9500 for the whole thing (legal and filing and other). The company will pay it for me now and If i leave volunteerly or been fired, then, I will have to repay the company. Can I agree? I am not sure how good this lawyer is. I remember someone posted a link before where you can search the records and commetns about a lot of lawyers. Just couldn't find it. Your help is appreciated.
