What happens when the outsource work isn't to your quality standards? You've wasted a lot of time already, and now you have to dispute it and waste some more time.
That's how my friend's service-based startup died before it even got out of the gate. He tried to outsource way too much overseas, not realizing the extremely low quality of work he would get (e.g. copy writing). He had to have a lot of it redone and burned through all of his cash before he got anywhere. (And he had a pretty weak business plan in the first place.)
Depends on what your goal is - if you've got the skills to do everything and/or are happy picking them up as you go along, while building your business - and in no hurry, then go for it...
