New York Resident's Comprehensive Background Search

I'm needing a thorough investigation on a person who used to live in New York. This encompasses researching their personal background, professional history, and obtaining their contact info. I can offer their full name, age, and occupation to assist with the query. It would also be helpful if you could dig into the industry they worked in, and any special skills they might have. Ideal candidates for this job would have experience in private investigation, people search, or relevant fields. Strong online research skills are needed.
