The first guy mentioned (holds jobs for 2 months, does nothing, gets paid then fired) would never be hired by me because I’d trash-can his resume as soon as I saw the length of his stay at his prior employers.

The hire-folks-to-do-my-work path is riddled with problems. What if those folks steal code and pass it off as their own work? Many companies today check very closely the licensing of software they reuse out of fear of being sued. Not knowing who is “writing” your code and therefore whether any of it is proprietary to another company or covered under some sort of license (BSD, GNU, GPL, MIT, Apache or more restrictive types) leaves the company wide open.
