How can I track down someone who has concealed his address?

Unless you are offering to find him for free, I need to know how to do it myself.
This guy has a UPS store on every single public record and even his driver license address, bank records,
He registered his car under a company name with his address in the UPS store as well.
Can anyone offer me some suggestions on how to find someone who does not want to be found and basically tells the world he lives in a UPS store?
John Miller,

it depends on why you want / need to find him?
Is it forlawful or unlawful reasons?
Send me a private message with more information so I can decide if I’m willing to help.
