Subcontracting out a Ridgid drain camera inspection turned into a $1200 nightmare

Hired a sub last week to run a Ridgid SeeSnake on a tough residential sewer line job, quoted the client $1800 total figuring I'd pocket $600 after his $1200 fee. Guy shows up late, botches the scope by getting it stuck halfway down the 4-inch cast iron stack, and now I'm out an extra $400 to fish it out myself with my own Milwaukee gear. FML, subcontracting these specialty plumbing gigs sounds easy on paper but always bites you in the ass when the sub isn't as sharp as you think.
