I would run a background check, dmv too. Being that they will be entering homes you want to make sure you can trust them. Not saying someone with a record isnt trustworthy. Another point would be looking for someone that is willing to hunker down when the work load becomes a lot for two and is willing to bust his rearend to make it happen. Not just a guy looking for a 40hr wk paycheck. Its hard finding the right guy, doubt it will be found on the first round. Good luck
