Ask HN: Freelancers, who are your customers?

Hi HN!

I'm a web developer, and I want to try to become a freelancer. After some research, I have found some people interested to work with me. They are individuals (not companies), and interested in small projects (blog, small e-commerce, CMS, etc.)

I think that's a good start! But now I'm wondering if it's possible to make enough money by only doing work for individuals. Should I start right now to focus on companies? Or doing small websites for individuals is enough? Can focusing only on these small projects can eventually bring me bigger customers in the end?

TL;DR As a freelancer, who are your best customers? Individuals, startups, small companies, big companies, etc?

Thanks!
