Like any business endeavor, if you don't have the skills to do it yourself, you need the resources to gain the skills, either through learning, networking and meeting people, or hiring someone. The scale you start at changes things too. We've spoken to a few grassroots ISPs that started 3-5 years ago by non-IT folks who just wanted to share with a few neighbors. Over the course of time they learned and grew the network and now they're at a couple hundred customers. Not big in the ISP sense, but it provided an essential service to their community and competes with [and steals customers from] incompetent, or at worse, anti-consumer incumbent ISPs.

If you have the passion, but not the IT skill set, be the banner waver. Be the leader of the endeavor. Use your passion to convert others. You'll find your talent.
