I don't live in Dallas haha.
The best tip I can give you when you're going local is to NETWORK like a fiend. Go to all of your local Chamber of Commerce events, LeTip, BNI, etc. There are tons of networking groups, especially in big cities, out there that let you meet other business owners. Yeah it costs some money, but its by far the most effective marketing tool for this kind of business.
When people by websites from me, they're doing it because they either like me, or I was referred to them by someone they like. Typically your local business owner will be of an older generation... so you're selling yourself, not your service. I've seen some shitty ass designers charge a lot more than me just because they have built trust with a client.
You can charge whatever you feel you're worth. You might want to undercut yourself just to build your client base. But as long as you're networking, you should grow pretty quickly.
