As a coder working on a startup, I can tell you one thing I've learned: coding (at least for me) is not the hard part. If your dream is to be an entrepreneur, here's my advice: learn to code and learn to sell, or find a great cofounder who knows how to sell.
A start-up that outsources its core competency is doomed. If you have an idea, and can't find a technical co-founder, learn to program yourself. PHP aint that hard.
Aren't startup people supposed to be all focused on getting results? If it takes paying someone else to hack up v1, rather than you spending time on it when you should be out selling or interviewing potential customers, etc, do that.
We never hear the stories from people who self-taught PHP or Rails for 6 months hacking on an idea only to then try to give it to users and have it rejected for multiple reasons. But they happen. Probably more than anyone realizes.
But as an aside, I definitely agree about selling. There seems to be this disdain for MBA/business types that don't build. As an engineer I can tell you that I have the utmost respect for skilled salespeople and I would definitely want one on my side when starting out.
