I'm also a non-technical founder, and I've got to say that you can't underestimate passion. Having a technical co-founder that believes in the project and works well with you adds that extra magic to the equation. As is always the case it's about team, team, team and it is difficult to find an outsourcer that will do anything more than exactly what is asked of them (if you are lucky). Sure it can be done, but having someone to question you, and predict problems before they arise is paramount.

Also as others have mentioned, it is tough to be agile with a continent and language barrier between you and the tech side of your company.
