I am looking for a man that is a legal practitioner and consultant, his name is Ozcan Buran, who lives and works in Istanbul,

This isn't really the proper forum for a question like this. Try a Google search. However, If this person randomly contacted you randomly via email, promising to pay a huge fee to use your bank account to move money into the U.S.A., it's an old internet scam and you should delete the email immediately (and call the police and your financial institutions if you were foolish enough to divulge any personal information).

I completely agree with Mr. Marshall. Best of luck.

You might want to consider hiring a private investigator.

This is not legal advice, but I would nor do any business with a company or individual who is outside of the jurisdiction of the United States civil or criminal justice system. The risk is too high for fraud.

Contact the Union of Turkish Bar Associations aka Türkiye Barolar Birliği as they list all licensed lawyers in Turkey. It is like the State bar associations in the US.
