Closed People finder help

meron po bang mga sites na pwede kong magamit for free sa paglolocate at paghahanap ng tao using emails or phone number, ang alam ko lng po kase is PIPL, linked in and facebook lang!
Any suggestion po will be a big help to me. Di po ako häçker, its part of my work po.. We locate person who still have liabilities with bank..

Ayun lng..salamat po in advance
