I guess you just don’t know until you try.
I’ve worked with several subs this year. From some, I’ve gotten great work – clean code, a job done in quick order and correctly. From others, I’ve gotten junk – messy code (which makes me cringe), a job abandoned in the middle or some problem that created more work than if I’d done it myself in the first place.
It just makes me really wary about depending on someone else to do my clients’ work for me. Very wary indeed.
