New submitter rchoetzlein writes "I am a software developer working independently for five years on various projects, and preparing to go public with my first product. Everyone is telling me I should make it open source. I would love to, but I just don't see how an early startup can afford to become profitable on service alone. My projects are no longer small-scale hobbies, they are large frameworks, and I need to make a living. Any ideas on business models that would allow me to open source while guaranteeing I can feed myself?"
