With me, I didn't start doing freelance work and then got clients, I had clients and quit my website production job I had with a small company.
I don't know what you have to offer, what it is worth, or how you should sell it.
What do you do that people pay money for? Who is making the websites for the small businesses in your area? What are they charging? Have you called all the places around you who do the things that you do looking for work? Just because folks don't have a sign out in front or a classified ad doesn't mean that they have no work for you.
As for me, I do a bunch of things that people need: I take pictures, can create good-looking wordpress themes, edit radio ads... and I have a bunch of folks who know who I am who call me to do these things. Those people didn't find me: I gave them my card or contacted them through craigslist, or I met them through friends. I charge a rate based on what the project is worth to me; I don't care what other folks charge, just how much I need to make off a project to make it worth my while. I don't ususally deal with legal stuff: at this point, I can't afford to hire a lawyer and I don't do things that cause me to hold substantial liabilities.
I have no idea what a domain name and some content would do for you, as far as a business. I get no business from my personal website; I have it up just to have something rather than nothing...
