I also do free prescreening of verifying employment, calling prior landlords, and open source internet of social media and state/county criminal court systems.

Also, google will teach you anything you want to know, especially small renovation/repair tasks.

Well I have my first Lead Geeks Amazing internet lead for $200!

He used a flip phone until last year, does not pay for internet and is in general very frugal and takes the extra money to put into investments. .You do not have to go with out internet!
