How long to wait before what? Before sending Vinny over? before filing a small claims court tort?
In all honesty, if the guy is not paying you then taking him to court and winning a judgement won't necessarily mean you get paid. Collecting a judgement from a dead-beat is just as hard as to get them to pay in the first place!
I recommend to just keep working with him on the payment. I have had clients pay me 6 months after the work performed because I worked with them, otherwise they would have never paid me. Being reasonable, nice and understanding can get you paid....being a jerk, an asshole or otherwise only brings more trouble.
Though, if you KNOW they won't pay and they have said as much, then sending Vinny over becomes an option
