Pick a single niche and become expert in that niche. The more specific the niche, the less work you'll get but the higher you can charge for the work you do.

Pick a single niche and become expert in that niche. The more specific the niche, the less work you'll get but the higher you can charge for the work you do. Get known as the expert in that niche. Write a blog on it, talk at conferences about it. I don't know what areas would be good now, but I've hired consultants in scheduling problems, network setup and management, security, and recruitment. If I had to pick an area that will never go out of style: security. Get good at being able to secure an online system and you'll never be hungry.
