this. between the time and hassle it takes to find someone reliable, just learn it yourself.
Many of us do have multi-tasking ability already.
However, there's a linchpin point that you reach, though, where your own time becomes intrinsically more valuable, and you have to outsource.
I try to keep more than one person at hand as my "go to" guys in a particular segment (writing, graphics, etc.), so if there is a problem with one, I have a backup plan.
The challenge is keeping that list of talent fresh and up-to-date.
