Find an under served niche and then build something to service that specific niche. I do just that about four years ago and have a stable client base of about a dozen clients who are all on our subscription based billing (instead of the costlier hourly billing) we have. Because of what we bill out, and the ability to work with my partners remotely even though we all live in the same city; we have zero overhead which increases our profit margin considerably. We started with websites and SEO. Now we're building enterprise level apps for these firms and they can't get enough of it. The industry we're in is also a tight-knight small community so once word starting getting around about the stuff we did and how we helped these other firms, we started getting a lot of calls. When we started, it was all cold calling, doing local industry conferences, and reaching out to their professional organizations and doing educational seminars and talks to increase exposure. Start small and then go after the big stuff. Otherwise, you're diving into a huge pool for competition. Focus on a small niche, own it, then duplicate that model to other industries.
