I will have to disagree on this, this advice is only good if your sole purpose is to make a quick buck. If you want to start a long term solid business than I suggest you treat people like humans and not like cheap interchangeable pieces as this post suggests.

Think of it this way, since you are not the one developing the application how much will you know about all its inner workings? When you will have customers and a critical bug in production who will solve it?

If you intend to outsource it I will suggest that you do not look for a cheap quick hack, but rather look for a freelancer with a decent rate, with whom you can build a working professional relationship. You want someone that will stick around for the long run and take responsibility for the software he develops, since building it is just the first step.
