Some services such as writing require a great deal of time. And, you can't just write out something quickly for a low price. Although other services can be offered quickly, such as bookmarking services done by software as much of it is automated.

Have you encountered buyers who put this demand on you? Such as manually write ten high quality articles in one day? Or, something equally burdensome?
