FYI, the filing of an employment-based petition will not result in lawful immigration status that will prevent deportation. That said, you could start a process and, if successful, the foreign national can re-enter the U.S. lawfully down the road. Depending on the facts of this particular case, "down the road" may mean several years, provided there are no convictions, etc. that result in a permanent bar.

No one that I am aware of quotes fees on a blog like Avvo.
The acronyms PWC/NO OL may be clear to a VA attorney, but not to me.
I suggest you meet with an attorney for a private consultation.

I agree with my colleague and add that not only would you need a petitioning employer, but the employer must pay at least some of the fees.
